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

Color changed immediately after 4 or 5 days of use. It detects when I go outside even when I'm not exercising, which is nice. However when I'm done it doesn't happen, sometimes after 2 or 3 hours when I'm done I realized that even if I'm watching a movie while lying on the couch it still counts. For sports, on the other hand, I used a different watch. This one only recorded 137 calories burned and the other 330. Other people I've worked out with recorded about 300 calories, so I believe this watch is either buggy or really inaccurate. I do not recommend.
