I was so disappointed when after charging the unit for the prescribed time that the unit wouldn't light up and work. I sent it back and a second unit was sent promptly. Imagin my surprise and disappointment when the 2nd unit wouldn't perform. I have had other brands of fitness trackers and it was the the same procedure, charge, download a app to help sync to phone, sync and go. Not with this, the unit never left the battery screen. I did return the second unit for credit. Btw, the Kronoz website was clunkie to use. ### ⭐ Do not waste your time *wink* *by C***N on Reviewed in the United States on January 5, 2022* I have gone through 2 watches and both so not work. The screen does not respond to touch. ### ⭐ you sent something that is not working *by P***I on Reviewed in the United States on February 7, 2022* my watch is not working very disappointed --- ## 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/92285086-mykronoz-zefit4-hr-fitness-activity-tracker-with-heart-rate-monitoring](https://www.desertcart.vu/products/92285086-mykronoz-zefit4-hr-fitness-activity-tracker-with-heart-rate-monitoring) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-10*
