For claiming to be a professional business, these people have a long way to improve their communication skills. I have to say that ghosting these students when it comes to serious inquiries is beyond unserious and disrespectful due to how much people invest in these classes. Truly be aware of your time and your money…

We appreciate all feedback from our valued customers, both past and present. However, after reviewing your comment, we see that you have never purchased from or had any direct experience with our business. Your review appears to be based solely on your frustration with someone else’s experience rather than your own. Trustpilot’s review policies emphasize that reviews should reflect genuine, first-hand customer experiences. Since your review does not meet this criterion, we kindly ask that you remove it, as it does not accurately represent our services. We hope you understand, and we appreciate your cooperation. If you ever decide to do business with us in the future, we would love to provide you with the exceptional service that our customers know us for. Thank you very much.

I was close to buying one of their online courses because my friends and I have been talking about starting a business, but when my friend signed up for the course, it turned out to be a complete scam. They never answered any of the inquirements nor did they send the products that were ordered from their website. Now I see that many of their products are sold out, but I get the feel that they never had the products to begin with. This has been a major setback in their process and I’d advice anyone to stay away from Grillz University.

Dear Chai, We appreciate all reviews from our past and current customers. However, after reviewing your comment, we see that you have never purchased from or associated with our business directly. Your review is solely based on someone else’s experience, not your own, which makes it invalid under credible review policies. Reviews should reflect genuine, first-hand experiences, and we kindly ask that you remove yours, as it does not accurately represent our services. Secondly, our online courses are not a scam. Once purchased, students receive instant access to all video content. We currently have 400+ students actively engaged in our course and community. If you'd like to verify this, we offer a free 7-day trial, so you can explore the content without any obligation. Regarding your friend's equipment order, we sincerely apologize if they experienced any delays. We have been on backorder for several months, which is why our equipment is no longer available for purchase on our site—to prevent orders for out-of-stock items and avoid situations like this. Please have your friend reach out to us directly, and we will do our best to resolve the issue promptly. We appreciate your understanding and hope that you will reconsider your review. Thank you very much. Best regards,

I am writing to express my extreme dissatisfaction and warn others about the service I have received from this company. Over the past few years, I have invested over $2,000 in ‘Grillz University’, including enrolling in one of their online classes and purchasing equipment totaling approximately $1,000 two months ago. To date, I have not received any updates or communication regarding my order. Despite my numerous attempts to reach out through all available contact channels, I have received no response. This lack of communication is unacceptable and unprofessional, especially for a business that presents itself as a serious institution within the jewelry-making community. I am deeply disappointed and feel deceived by this experience. Not only has this situation cost me a significant amount of money, but it has also negatively impacted my trust and aspirations. Insane to take advantage of people who are passionate about pursuing their craft and dreams. DO NOT spend your money on anything this so called company has to offer.

Dear Gangina, We sincerely apologize for the delay in shipping your equipment. Unfortunately, due to all our equipment being on backorder, we were unable to fulfill your order as expected. We understand how frustrating this must have been, and we truly regret any inconvenience this has caused you. We have officially processed a full refund for your order, and you can expect to receive the funds within 7 business days. We have also emailed you a PDF copy of the issued refund for your records. Additionally, we regret that our shipping department did not handle your issue in a timely manner, and we are taking steps to improve our processes to ensure this does not happen again. We genuinely appreciate your patience and hope to have the opportunity to work with you in the future. If you could kindly update your Trustpilot review to reflect that we have rectified this issue, we would greatly appreciate it. Your feedback is invaluable to us. Please feel free to reach out if you have any further questions or concerns. Best regards, Terrell

If I could give 0 stars I would!!! I purchased a 2 day class for June. The June class got rescheduled to August 3rd-4th. That days comes, I’m in Charlotte at the address they gave us to meet and it’s an apartment complex!!!! I tried calling every number I could find, I emailed, I even contacted them on Instagram where I first seen their content. The person running the Instagram page seen my messages and didn’t respond! I had to continuously send messages to their instagram account and try to video call before the person said anything! They sent a message saying I contacted a team member they’ll speak with you shortly. I received an email saying that they’re sorry and the class was canceled but somehow they forgot to email me about it! They offered a refund or access to their 5 day class with no extra charge. I said I wanted my refund. They sent out a jotform I filled it out same day. They said the refund process take 1-2 weeks well it’s been well past that!! One person called me and said they’d be working on my refund by Tuesday 3 weeks ago and they have still not sent me my money! I’ve called, left messages, emailed and tried to contact them on Instagram and still haven’t been contacted! I highly pissed. They’re definitely scamming so stay away, save your money and go somewhere else!

Absolute Scam. The in-person course was an absolute scam. classes were scheduled for 8am-5pm. over the 5 day "master" course we did not start any day before 10am and were out of class by 2pm. The information taught to us was the same information you could find on Youtube. The biggest selling point for me to take the course was the included equipment. However, that equipment was never sent out to me or any of the students in our class (it's now 6 months later). Our emails are ignored and when we do get a response they are filled with excuses as to why they have yet to send our equipment. Terrel and the entire GU team are frauds. if you are smart you will stay clear and save your money. if you want to learn how to make grillz there are several actual jewelry schools that teach grillz and everything else you need to know about jewelry.
