Easily attaches discreetly to the back of a 15 year old stereo. Turn on the stereo and connect to my phone via bluetooth and I can play anything. I had no issues with static electricity or shutting down after 10 minutes. You have to re-pair the Bluetooth connection every time you turn on the stereo, but that's acceptable to me. Otherwise, it may try to connect to all phones that are in range. There may be pricier options to auto-connect or prevent disconnects, but for the price I paid I'll be satisfied.
