Customers say
Customers find the biometric monitor works flawlessly out of the box and is compatible with various equipment, including treadmills, bikes, and Landice L7 machines. They consider it a great fitness tool that keeps track of heart rate, and one customer mentions it’s particularly useful for swimming workouts. The monitor’s durability receives mixed feedback – while some find it long-lasting, others report it only lasts about 1.5 years, and the battery life is criticized for being poor with a non-replaceable battery. The heart rate reading and connectivity features receive positive reviews.
