Completely awful. They sell cheep crap that does not work at all or works for a week and breaks. If you want a gag gift or something that does not need to work longfor the fun of it. Just plan on one to two months to get it. For example, I bought an activity monitor for about $12. The broken English on both the watch and app was amusing. It seemed to take accurate blood pressure and monitored steps fairly well but the app was always glitchy. After about 10 days it would no longer take vitals and said to make sure have right to wear. Never worked right again.
