So it was understandable I was concerned about buying yet another. But I felt I did need one and so I figured third time lucky...or quit. I can honestly say I am delighted with this fit-watch. So very easy to set up, fits perfect (though it was a bit awkward at first one handed but just use the arm of the chair.) It tells me everything I want to know, even down to my quality and length of sleep. And it resets itself every morning. Very impressive. Long battery life, about 7 days, and also has a heart monitor which is brilliant. Any drawbacks? Yes, I am concerned I might wear out the strap and it can't be replaced. Does that bother me? Not at all. The strap is of a better than expected quality so won't be wearing out any time soon. I am just satisfied to have finally bought what I wanted and needed. Wish I had found this one first. Looks good on as well, as it is a slim-line strap, nothing bulky. So good my husband is now seriously thinking of buying one, and he doesn't usually go for this type of thing. Delighted with my purchase and would most definitely recommend, both the watch and the seller. ### ⭐⭐⭐⭐ but as I've got used with it and how it works I feel it does a good job at recording the heart levels *by J***Y on Reviewed in the United Kingdom on 2 August 2017* I bought this a while ago, after initial issues with the heart monitor, I contacted the seller who gave me advice and instructions on this subject. The heart monitor takes time to get the pulse, so don't be to hasty with the device. To be honest, at first I felt the heart monitor is a bit of a gimmick, but as I've got used with it and how it works I feel it does a good job at recording the heart levels. It does a good job at recording steps but any movement in the arm/wrist will be counted as a 'step'. But as they say ' you get what pay for'. I gave it 4 stars as I feel 5 would be flattery. ### ⭐⭐⭐⭐⭐ Good if you like stats. *by H***N on Reviewed in the United Kingdom on 7 June 2017* This is my first impressions of the smart bracelet - fitness wristband.It is light and fits well.I love stats, so this feeds my addiction nicely.It's easy to download the app and then you just pair it with your phone.When you have installed the app, the user interface is easy to understand. It will show the amount of steps you have taken, your heartrate and sleep pattern.I will post another update in a couple of months when I have built up some more stats. --- ## 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.vu/products/48599530-smart-bracelet-fitness-wristband-with-heart-rate-monitor-fitness-activity](https://www.desertcart.vu/products/48599530-smart-bracelet-fitness-wristband-with-heart-rate-monitor-fitness-activity) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-12*
