It works perfectly and the charge lasts for a very long time. I charge the watch about twice per month. I wish the display was brighter for daytime as it is not easy to read unless you find a heavily shaded area. However indoors and at night the display is very easy to read. I have counted my steps and see that the pedometer is very accurate. The heart rate monitor is perfect, and the blood pressure is OK but only 80 to 90% accurate, which I think is pretty remarkable, since it reads your blood pressure from your finger. ### ⭐ Complete and total waste of money I should have sent these back when ... *by S***N on Reviewed in the United States on March 1, 2018* Stay away from these watches I bought two of these they are okay until you put one on then realize it's no longer wrapped around the wrist.. Complete and total waste of money I should have sent these back when I got them.. These guru cheap ass bands should be outlawed in this country!!! They won't last you 2 weeks if worn day to day !! They would be doing the consumer a huge favor by outlawing bands that don't stay wrapped around the wrist!!!!! ### ⭐⭐⭐ Should've bought the Fitbit! *by S***H on Reviewed in the United States on December 12, 2017* The watch seems to work good. I gave it a 3 because the watch band cannot be cleaned. I made the mistake of choosing white, big mistake. I've tried everything I can think of to clean the dirt on the edge of the band & nothing works. I wore it to work for about a week & it was filthy. I'm very disappointed that it can be cleaned nor are there replacement bands. --- ## 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.vn/products/71263905-onston-smart-watch-bracelet-waterproof-ip67-fitness-tracker-heart-rate](https://www.desertcart.vn/products/71263905-onston-smart-watch-bracelet-waterproof-ip67-fitness-tracker-heart-rate) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-16*
