Review on 💓 Polar T34 Transmitter HR Chest Strap: Model 392027802 by Kettler Fitness - Accurate and Reliable Heart Rate Monitoring by Brandi Stone

I can't complain about what I bought as it is exactly what I need. I will complain about the design which has nothing to do with Revain or the seller hence 5 stars. I really wish I could just replace the battery. I watched the video and tried it, but ended up damaging the original tape. Well, I hope to be good with this one for another 7 years.
