The watch time display can change from digital numbers or digital pointers, nice option of having different styles. The steps counter seems way off. I am on my feet virtually all day and watches have shown that i average 9,000 steps per day. This one says around 4,000 per day. The sleep function is also a let down, it monitors sleep pattern between 10:00pm and 7:00am which will suit the majority, but in my case i often go to sleep between 9:00 to 9:30pm as i get up really early. So although my target may be 7.5 hours, any sleep before 10:00pm will be ignored, therefore missing my target and giving incorrect information.The blood pressure and Heart Rate appear to be excellent. This one does it different to the rest as it has 2 sensors on the front, you place your index finger over them for 30 seconds. It appears to be accurate. The app looks good showing all the stats and even having an option of printing out a health report.If they sort out the steps and sleep issues then this would be without doubt the best fitness tracker that i have seen. ### ⭐⭐ Not as good as the adverts says!! *by A***T on Reviewed in the United Kingdom on 5 November 2017* The company quickly responded to my review which was not a good review. They did send a replacement bracelet. but the same issues are with the replacement. It does not always connect to the APP. The ECG function now doesn't work on either bracelet and the accuracy of the BP is not at all accurate. I was not expecting medical accuracy, but to use the readings as a guide. All in all, don't waste your money if you want to use these functions. Disappointed. You can have both back!! ### ⭐ Cheap FitBit! *by N***E on Reviewed in the United Kingdom on 14 January 2018* I have used this for about 6 weeks. Generally disappointed with accuracy. Not recommended. --- ## 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/68113899-pulse-knife-fitness-activity-tracker-wristband-wrist-band-armband-pulsometros](https://www.desertcart.vn/products/68113899-pulse-knife-fitness-activity-tracker-wristband-wrist-band-armband-pulsometros) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-04*
