Hello I am writing this review because I have tried dealing with Gravastar's customer service. I purchase Christmas gifts throughout the year. Around this time last year (June), I purchased two Mercury X Pro mice as gifts. I gave one to my son and one to my daughter as presents. My daughter used her mouse maybe 8 hours total, and the scroll wheel broke off, making the unit unusable. I sent pictures and a short video, and all I got was the runaround. They said it's past the one-year warranty, so they are not obligated to replace it. Now I have purchased over $2000 of their products, Speakers, docking stations, and chargers, all as gifts to my young adults and clients of mine. We had issues with the docking stations recharging in the past; they sent a fix, and it worked fine. Now they've got me taking apart the mouse and sending pics of the inside. It's clearly a manufacturer's defect. I have had mice for years without any issues. They even admit they have seen this issue before. Now all I get is the runaround. I won't be purchasing anything from this company again. They have cool stuff, but it just doesn't work properly. Now I am out $130.00 because it's over a year. It sat in my house for 6 months before I gave it as a Christmas gift. In the pics I sent, it looks brand new. Update:06/18/2026 Here is the email Gravastar sent me yesterday morning. They seem more concerned with the review than with the problem at hand. "Where did you send the package back? We did not provide the return address previously. We must declare that address confirmation is not another tactic for delaying and denying claims. It is necessary step for all of the after-sales process. We will send the new package to you today at the following address: And we received a notification today that you left a 1-star comment on Trustpilot. Could you please remove or revise the comment"? I provided them with my tracking information when I sent the defective mouse back to them without their authorization. I sent it back to the warehouse it came from. I want them to physically see that the mouse was brand new and had fewer than 8 hours of use. They did not provide any tracking information yet. I feel confident they will. But why would you ask me to remove the post on Trustpilot? As a businessman myself, if this ever happened to me, I would make sure the client was happy with the final outcome before ever asking for an edit to a complaint post. I will keep Trustpilot updated if I receive a new mouse and if it works as it should. Updated 06-18-2026 2nd post Here is their latest response I received early this morning. I actually don't believe they have an engineering and quality control team based in a warehouse in Henderson, Nevada, and they are going to look at this on Saturday when it arrives. But the good news is they are sending a new one as they should. We will see. Here is the email below, more AI BS. "Thank you for your reply, and I sincerely appreciate you sharing the return tracking details and address with us. First and foremost, I want to extend our most sincere apologies for how the previous communications made you feel. It was never our intention to sound dismissive or to show a lack of empathy, especially knowing that this was a special Christmas gift for your children. We truly value you as a loyal customer who has supported GravaStar over the years, and we take your feedback about our customer service tone very seriously. We will absolutely use this experience to do some internal soul-searching and improve our support training. We want to make things right for you immediately. Your replacement package has indeed been dispatched, and here is your official tracking information to monitor the shipment: • Carrier/Logistics Provider: Cirro • Tracking Link: Regarding the mouse you sent back to our Henderson, NV warehouse, please rest assured that we will not throw it in the trash. Our engineering and quality control teams will personally inspect it as soon as it arrives this Saturday. Your feedback about the scroll wheel issue is crucial to us, and examining your device will help us identify potential manufacturing or component vulnerabilities so we can prevent this from happening in future batches. We are fully committed to ensuring your children can enjoy their gear smoothly. Once the new package arrives and you have had a chance to verify everything is in perfect, brand-new condition, would you be open to re-evaluating your experience or updating your comment on Trustpilot? Your satisfaction means the world to us. Thank you again for your patience, your constructive criticism, and for giving us the opportunity to correct this for you. 06/24/2026. I would like to thank Gravastar for sending a new Mercury mouse. Received it yesterday and works just fine.

Thank you for sharing your feedback, and we sincerely apologize for the frustration this experience has caused you and your family. We completely understand how disappointing it is to encounter an issue with a gift, and we deeply value your incredible loyalty as a customer who has purchased over $2,000 of our products. While the 1-year warranty period had indeed passed, we want to reassure you that our goal is always to make things right. As our customer service team recently communicated to you, we have already approved a free replacement solution for your daughter's Mercury X Pro mouse to resolve this manufacturer defect. We apologize if the previous troubleshooting steps and requests for internal photos felt like a "runaround"—our technical team uses these details to improve future product designs, but we realize it caused unnecessary hassle for you. Your replacement is being handled with priority. If you have any further questions or haven't received the updated tracking details yet, please feel free to reach out to us directly at [email protected]. Thank you again for your patience and for helping us improve. Best regards,

Das erste Bundle mit Maus und Tastatur was bestellt wurde per Express befand sich 1 Woche in nicht bearbeitet zustand und obwohl per Paypal Bezahlt hies es dann es gäbe ein Problem mit der Kreditkarten Abrechnung. Der Support hilft 0 und schreibt immer dieselben holen nichts bedeutenden Sachen. Danach gab es einen Fehler im Lager. Letztendlich kam das Bundle viel zu spät und Erstattung der Expressgebühr gab es nicht. Vor 1 Woche erneut eine Tastatur für meinen Mann bestellt per Express Versand. Auf der Website wird der sofortige Versand innerhalb Deutschlands Beworben. Natürlich wurde das nichts. Support angeschrieben keine Antwort. Negativ Bewertung Boom oh wunder Antwort. DHL Sendung Sendungsnummer: xxxxxxxxxxxxxxxxxxxxxxxxxxxx Die Sendung wurde elektronisch angekündigt. Mi, 10.06.2026, 18:24 Uhr Dass der Status, obwohl vom Support eine sofortige Klärung und Versand zugesichert worden ist. Für die Erstattung der Express Gebühr wurde in der ersten Mail das Löschen der Negativbewertung vorausgesetzt. GravaStar Support-Team gravastar.de>; Kurzfassung Das Support-Team entschuldigt sich bei der Kundin für die Verzögerungen beim Versand ihrer Tastatur. Als Grund werden erhebliche Engpässe bei einem externen Logistikpartner (3PL Warehouse) angeführt. Das Unternehmen sichert zu, den Versand mit Hochdruck zu forcieren, den Paketstatus in Echtzeit zu überwachen und die bereits zugesagte Rückerstattung der Versandkosten für drei Bestellungen zu veranlassen. Die Nachricht erfolgt als Reaktion auf die massive Kritik der Kundin bezüglich der ausbleibenden DHL-Übergabe und ihrer angekündigten rechtlichen sowie öffentlichen Schritte. Dein Feedback zählt Das war die 4 Mail und oh Wunder nichts. Keine Übergabe der Ware an DHL und somit auch kein Versand. Es wird ein Schweinegeld für die Produkte verlangt. Der Support ist mehr als unfähig da immer dieselben Nachrichten wohl anscheinend eher 'ne KI als Mensch und gekümmert wird sich um gar nichts. Ist ein reines Kunden verachtendes Verhalten. Für die erste Bestellung gab es keine Rückerstattung der Expressgebühr. Fazit Schöne Tastaturen richtig Schlechtes und Kunden verachtendes Unternehmen. Es wird sich um nichts Gekümmert, haltlose Versprechen gemacht die nicht gehalten werden, Geld nicht der Kunde zählt. Software die Tastaturen nicht erkennt und Erstattung bekommt man auch nicht. Wer auf Ärger Stress und Frust steht hier bestellen, wer Spielen will, sollte sein Geld in andere Unternehmen stecken.

I am Andy, the head of GravaStar's online store. I am personally reading your review, and I want to sincerely and deeply apologize for the incredibly frustrating and unacceptable experience you’ve had with us. First and foremost, I want to clarify a critical mistake made by our support team: We DO NOT require or tolerate forcing customers to delete a review in order to receive a refund. This was a severe miscommunication and a violation of our brand values. I have personally stepped in to address this with our team to ensure it never happens again. To make things right immediately, I have personally authorized and processed a full refund for the Express shipping fees for ALL your orders today. You should receive the Shopify refund confirmation email shortly. Regarding your current order (which is indeed stuck at the DHL electronic announcement stage due to a severe issue at our 3PL warehouse), I am manually coordinating with our logistics manager right now to ensure your package is physically handed over to DHL and dispatched without any further delay. I understand your trust in us is broken, but I am committed to fixing this for you personally. If you have any further questions or if the refund hasn't reflected, please email me directly at [email protected] with "Attn: Andy" in the subject line, and I will handle it myself. Sincerely,
Dennis A.
2 Mal dort bestellt einmal ein Bundle mit Maus und Tastatur. Express bezahlt und 14 Tage gewartet bis es ankam. 2. Mal nur Tastatur vor ein paar Tagen bestellt per Express Versand erneut und 2 Tage bis die Bestellung bearbeitet wurde.3 Tage mittlerweile steht bei DHL die Sendung wurde Elektronisch angekündigt aber nichts weiter. Die 9 Euro für den Expressversand wurden nie erstattet. Auf der Website wird mit sofortigem Versand geworden. Wer sich veraschen lassen will ist hier gold richtig!!!!! Aktualisierung Der Support meldete sich nicht auf meine Nachricht aber auf die Negativbewertung.Es wurde der Sofortige versandt angepriesen was nicht geschehen ist.Sendungsname: DAZ Lager & Logistik GmbH Sendungsnummer: Die Sendung wurde elektronisch angekündigt. Mi, 10.06.2026, 18:24 Uhr Adressiert an: Heute is Freitag!!! Am Montag Bestellt!!! Und immer noch nichts!!!!!!! Des Weiteren wurde man aufgefordert für die Erstattung der Expressgebühr die Negativbewertung zu löschen. Nach dem Strafgesetzbuch ist das Erschleichung und Betrug Geld für den Express Versand zu kassieren und diesen nicht durchzuführen und das Geld nicht zu erstatten. Angeblich Fehler der Lager Mitarbeiter. Normal müsste jemand das Teil als Entschuldigung persönlich Vorbeibringen oder aus Kolans sagen eh unsere Kunden sind uns wichtig wir haben einen Fehler gemacht hier is die Tastatur und eh für die Unannehmlichkeiten kriegst den vollen Kaufpreis zurück oder zahlst nur 50%

We sincerely apologize for the frustrating experience you’ve had with your recent orders and the unacceptable delays in shipping, especially since you paid for Express shipping. This is absolutely not the level of service we aim to provide. We completely understand your frustration. To make things right immediately, we will fully refund the Express shipping fees for both of your orders. Regarding your current keyboard order, our support team is investigating the hold-up with DHL to find out why it is stuck on the electronic announcement status. We want to get this moving for you right away. Please kindly send a quick email to our customer service team at [email protected] with your order numbers so we can process your shipping refunds and provide you with an immediate status update on your package. Thank you for your patience, and we are committed to resolving this for you swiftly. Best regards,
