Review on POLAR H10 HR Sensor: Bluetooth Enabled, 🏋️ Black, M-XXL – Advanced Accuracy for Heart Rate Monitoring by Elizabeth Brooks

Bought in May 2020 and after about 6 months the device stopped working with a fully charged battery. It works for a week and then won't sync or connect to Bluetooth. I ended up replacing the battery every week and ended up with a box full of batteries that were 90% charged. I started the warranty process and Polar lets me send them back for my money. 14 dollars. THEN - this is the most ridiculous part - even though the H10 comes with a 2 year warranty, they send me a $60 repair bill! So I sent them a broken H10 for $14 to keep. There's no way I'm paying an extra $60 for that junk. Absolutely terrible product and even worse customer service. Avoid at all costs.
