The monitor was working great until I had to charge it. I connected the charger and then placed the monitor in the charger. Nothing has happened. I tried realigning the monitor but still nothing. Nothing lights up and hrm doesn't work. Because this problem started after the first successful use of hrm, the return period for Revain products has expired. I emailed the manufacturer but never received a response. When it worked hrm was great. However, since it doesn't charge, it's now unusable. Livlov support does not exist. Based on my experience, I advise against buying this product.
