Review on Cubitt CT1 Series 2 Fitness Tracker with Alexa: Heart Rate, Stress & Blood Oxygen Monitoring, 14 Sports Modes, Sleep Tracking, Waterproof by Jimmy Scaturro

I really liked the product at first, same features as the Charge 3 Fitbit for 1/3 the price but annoying that it charges every 4 days. I order a replacement and the replacement has the same problem. The battery only charges up to 90% and dies. Had to plug it back into the charger so it could charge the rest of the way. Multiple times! In the end gave up and sent back both the original and the replacement.
