Never received a product. Horrible customer support. They said they would "look" into my order and have not

The bottle we received feels extremely cheap. For the price, I’d expect much higher quality products. The main lid spins and when I finally get it fastened on, I can’t get it off again, the alternate top options are incredible hard to open in general. Customer service has been completely unresponsive after multiple attempts. I wouldn’t waste your money on these water bottles. I’m extremely disappointed.

Ordered a 3 pack, the water taste changes when used and if water is in the bottle for a few hours it gets a horrid plastic taste Reached out to customer service who offered silly options. And lucky enough I paid through PayPal and won and claim against them I now got a refund and 3 useless bottles to discard. I wanted these for so long finally bit the bullet and the initial look of plastic seam was sad. I went a few days without using it with the disappointment only to take it to work the first day and felt I'll due to the plastic taste of the water. I don't know what the hell materials this things made from but I'm guessing it's not good grade and this product should be professionally recalled!

The lid cracked, making the bottle unusable. The plastic seems to be of poor quality because I have hardly used the bottle. Support is only offering me a small discount to buy a new bottle. Considering the price, the quality and service are not up to standard.

Absolutely unacceptable after-sales service and absurd return policy. I purchased a bottle from TMB ModularBottle expecting at least the same quality as a previous smaller version I had bought before. What I received was clearly inferior: the lid spins loosely without functioning properly, and the overall construction feels cheap, flimsy, and overly plastic-like. When I contacted customer service to report the poor quality of the product, their “solution” was outrageous: either accept only a 50% refund, or return the item to the United States at my own expense for a full refund. In practice, the international return shipping cost is so high that it makes the supposed full refund almost meaningless. So let’s be clear: if you receive a poor-quality product, you may be left with two terrible options — lose half your money, or spend an unreasonable amount just to send it back overseas. This is not a serious way to handle a legitimate quality complaint. A return policy like this is unfair in practice and completely unfriendly to international customers. Buyers should think very carefully before ordering from this company, because the real issue is not only the product quality, but how the company behaves when something goes wrong.

Ich kann wirklich von diesen Flaschen abraten. Ich habe 2 gekauft, weil ich anfangs total gehypet war. Die 1. Flasche kam mit gebrochenem Glas an, die 2. zunächst gar nicht. Nach Kontakt mit dem Support wurde ein Ersatzglas für die 1. und dann die 2. Flasche geschickt. Das Konzept ist eig total cool, wenn ich nicht nur über Nachteile berichten könnte: Die Einzelteile der Flasche sind nicht von hoher Qualität, es ist Alles aus einfachem Plastik. Alle Teile haben einen unguten Geruch, selbst nach mehrmaligem waschen (sogar nach einem Geschirrspülgang). Viele Teile quietschen ohrenbetäubend laut beim zusammendrehen und lassen sich teils nur sehr schwer anbringen. Ich bin so enttäuscht davon. Der Support war zumindest freundlich, aber das kann ein mangelhaftes Produkt leider auch nicht retten. Keine Empfehlung!!!

Vielen Dank, dass du dir die Zeit genommen hast, deine Erfahrung so ausführlich zu schildern – auch wenn es uns sehr leid tut, das lesen zu müssen. Was du beschreibst, entspricht nicht dem Standard, den wir an uns selbst stellen, und wir verstehen deine Enttäuschung absolut. Gebrochenes Glas bei der Lieferung, eine verspätete zweite Sendung, anhaltender Geruch trotz mehrmaligem Waschen und quietschende Teile, die sich schwer zusammenbauen lassen – das alles sollte nicht passieren, und wir entschuldigen uns aufrichtig dafür. Es freut uns, dass unser Support-Team zumindest beim Ersatz helfen konnte – aber du hast völlig recht: Guter Kundenservice kann ein mangelhaftes Produkt leider nicht ersetzen. Etwas, das wir gerne klären würden: Wir haben kürzlich eine überarbeitete Version der Flasche veröffentlicht, mit deutlichen Verbesserungen am Zusammenbau – die Teile lassen sich jetzt merklich einfacher und geräuschloser verbinden. Es ist gut möglich, dass du noch eine ältere Version erhalten hast. Könntest du uns unter [email protected] deine Bestelldetails zukommen lassen? Wir würden gerne prüfen, welche Version du hast, und schauen, was wir für dich tun können. --- Thank you for taking the time to share your experience in such detail – even though we're truly sorry to read it. What you've described is not the standard we hold ourselves to, and we completely understand your disappointment. Broken glass on arrival, a delayed second shipment, persistent odor even after washing, squeaky parts that are difficult to assemble – none of this should happen, and we're genuinely sorry it did. We're glad our support team was at least able to assist with replacements, but you're absolutely right that good customer service cannot compensate for a product that falls short. One thing we'd love to look into: we have recently released an updated version of the bottle with significant improvements to the assembly mechanism, making it noticeably easier and quieter to put together. It's possible you received an earlier version. Could you reach out to us at [email protected] with your order details? We'd like to check which version you have and make sure you're not left with something that doesn't meet our current standard – and explore what we can do for you from there.

I ordered a bottle from the website and my point is not the customer service that was bad. The modular cap just didnt come of when I wanted to take it of for the first time. After using rubber gloves and a lot of force the cap came off. Used the bottle like 3 times and literally the same problem happened. After screwing the the same modular ring back on with not much force at all the cap just refused to come of. I have tried everything, even using tools to get the cap off but it just was stuck again. Broke the bottle trying to get the ring off. Terrible product
