Review on 💪 Spree Bluetooth Fitness HR Tracker by Eric Wright

The product is not worth a penny.1. Device: It cannot stay in place on the strap, it just stays where it should be by the force of your forehead on the strap.2. Software: An entry-level software engineer wouldn't design it that way, it has very limited information, it doesn't show body temperature, it doesn't show a heart rate curve over a training period. , it just gives you your average heart rate, it doesn't give you a calorie burn curve, it just gives you an average. I wouldn't pay a dime for this product.
