Review on Wafa Fitness Tracker - Heart Rate, Blood Pressure Monitor | Waterproof, Bluetooth Sports Smart Watch | Sleep Monitoring, Activity Tracking Pedometer Watch for Kids, Women, and Men by Chad Carter

For the money this is the best watch of its kind I could find. I've literally tried about 15 different Bluetooth-enabled Android watches in the $300-$19 range and this is the best. Everything works as advertised. I couldn't understand how the blood pressure test could be right, but I tried it in the doctor's office, right after the official reading, and it was only a few points off. Very impressive. I would definitely not recommend trying this watch in water at any depth. I tried it in very shallow water and the watch went off - unusable. This is very unfortunate, but the company was very considerate, supported their product and replaced it immediately even though it took a few weeks to ship. Excellent watch in terms of value for money. good company I would buy again.
