Oukitel BT80 Review

The service was excellent; I received the watch two days after placing the order. I am very pleased with the watch overall, especially for training purposes where it truly excels. However, I purchased it primarily for sleep tracking, and I am disappointed with its performance in this area. The watch does not accurately record waking times, which results in incorrect sleep duration data. For instance, if I sleep for eight hours but wake up after six hours and then fall asleep again, it only registers two hours of sleep. On a positive note, the battery life is impressive, lasting 30 days with the screen off and without using the massage and notification features. Despite the shortcomings in sleep tracking, I find the BT80 to be a good value for the money.
