I've had this product for over 6 months now and at first, i really enjoyed the product for its bluetooth capabilities and usb car charger.
However, in the past two months, i've noticed that my product continually disconnects after 10 or so minutes from my bluetooth on my iphone. I've had the iphone 6s, 7, and 8 all connected to the product at separate times and they've all continually disconnected every 10 minutes. I can't even get a full music session on my commute to work without it disconnecting.
Also, I have this strange squeaky "eeeeeeeee" noise coming from my speakers whenever I'm connected to transmitter that tends to get annoying as well.
Overall, not happy with the product. I'll be looking elsewhere for another FM transmitter in the market.
