Bright color screen. I liked the clip on the strap (compared to buckles on watches). Snap-on contact charger (not wireless). I had a bit of difficulty getting call and message notifications to show. Lightweight alternative to full-featured smartwatches (note, this is not an Android Wear based bracelet, and there are no "apps"). ### ⭐⭐ the display is not good you can look at the pixels when you swipe ... *by A***R on Reviewed in the United States on January 2, 2018* Is hard to download the app because it's not on the Playstore, you have to downloaded from the internet and change a lot of security setting on our phone, the display is not good you can look at the pixels when you swipe it, I could receive calls notification but never SMS notifications. I just returned, not happy at all. --- ## 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.jp/products/48850785-bithealth-z4-smart-bracelet-with-heart-rate-monitor-activity-tracker](https://www.desertcart.jp/products/48850785-bithealth-z4-smart-bracelet-with-heart-rate-monitor-activity-tracker) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-04*
