I tried everything you told me to do in the website. But still not working. Also, no one reply my email or help to solve this. Return exchange will need to wait almost two months... I can't believe it!!! Just terrible. ### ⭐⭐⭐ 3.0 out of 5 stars Could do without - Don't recommend unless you just want to spend $ *by P***L on Reviewed in the United States on August 24, 2016* Packaging: Unit came in attractive mostly paper based packaging (much better than plastic)Initial Setup: Unit was easy to pair, update and connectAccuracy: Out of the box, it was pretty accurate. I would drink one ounce and it would record one ounce. The Next morning it seemed to be missing a few ounces here and there. Not sure if its a Bluetooth issue or what. Better to be over hydrated than under hydrated I guess.Cup: The exterior is attractive and modern but only when its clean. The matte white porous surface stays dirty. My cup holder rubber rubs off and permeates the surface and as does my makeup, lipstick and lotion. Water alone will not clean the exterior.08/30/16 Update: The surface is so-high-maintenance (unless you don't mind the dirty look). Using cup holders, placing the Vessyl in purses or gym bags is going to make your cup look filthy. Traveling with a travel pouch has become a must since I am tired of soaping up my Vessyl several times a day to keep the matte white surface clean.Pryme algorithm: I am not confident about the Pryme calculation. At the moment, I am about 8 oz behind my normal water consumption, yet the Vessyl app tells me that I'm at 135% of my Pryme and will be there for the next 7.5 hours. What??? I will need at least another 24 oz during the next 7.5 hours and that's just to keep me from extreme dehydration!08/25/2016 Update: To address the issue with Pryme not requiring me to drink as much water, I changed my lifestyle from "Mostly Sitting" to "Always breaking a sweat". I workout a few times a week (at most and I sync those workouts to the app) and I sit at a desk all day. While is is a bit better, I still find the calculation to be less than my true water requirements.Lid: This seems spill proof enough for my needs. I wouldn't put it in a backup sideways or upside down, but its fine for upright commuting. The lid was hard to remove when I first received the unit but after watching a few videos I was able to remove it. Once you get used to how the lid works (and you realize you are not going to break it) its totally fine.08/25/2016 - I tipped the Vessyl sideways and upside down and it did not leak. This gave me confidence to place it upright in my purse. Well, I forgot about it,laid the purse down carelessly and returned an hour later to find water had leaked into my purse. It is spill resistant, not spill proof. Their FAQ's are confusing on this matter as one article claims "Spill-Proof" and another article says "not fully spill-proof".App- The app is pretty good. It would be great if told me how many oz I drank in a day. Currently I have to go to Health Kit to find that information.Taste: I notice at times a highly chemical taste in my water. I think it comes from the matte white plastic exterior as the interior is hopefully non-leaching glass.In Summary,The occasional chemical taste, along with the overall high maintenance of the Vessyl are enough that I would't recommend this product and I wouldn't purchase again. I like it, but certainly not $120 worth plus effort. $60 would be more reasonable price point for the product. ### ⭐ 1.0 out of 5 stars I had been SO excited about this and thoroughly enjoyed it for about 3 weeks when it suddenly stopped ... *by C***H on Reviewed in the United States on October 26, 2016* I had been SO excited about this and thoroughly enjoyed it for about 3 weeks when it suddenly stopped functioning. I had read about this issue happening to others, but like most, assumed it wouldn't happen to me. For the past three weeks I have been contacting their customer support via the app and their website and have heard nothing. I checked their Facebook page and the last posting was from November 2015. I am extremely disappointed in this product and their service. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/31114465-mark-one-pryme-personal-hydration-tracker](https://www.desertcart.co.uk/products/31114465-mark-one-pryme-personal-hydration-tracker) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
