Fitness Tracker, Swimming Watch with SpO2 / Heart Rate/Sleep/Blood Pressure Monitor for Teenager and Adult, Blue

lousy the clock, does not connect to the cell phone ... bad buy ... do not waste your money ... do not provide a good after sales service ... should drive the Amazon seller

I purchased 2 of these, 1 per kid. The biggest allure with this watch was the price (they were for teenagers) and the fact that they are waterproof. I have 2 swimmers who are in the pool for anywhere to 1 - 3 hours per day depending on the season so waterproof is important. One watch has held up for the last months and is still going. The other watch lasted 2 -3 weeks before it stopped charging and stopped working as a result. I did return it but was (and still am) disappointed that it didn't last. Also the black around the edges is paint and has started coming off. Wouldn't buy this again
