iSimple - Bluetooth Hands-Free Car Kit - Black

I purchased this with high hopes of bridging the gap between my 1990 Mercedes and current Bluetooth technology. The Bluetooth works by small, rechargeable battery in the cassette unit. I charged up the unit, and it played pretty well. If you jiggle it, so the unit’s contact with the tape playback head is solid, you can get a serviceable sound. After about an hour, the battery died, so no Bluetooth, until it’s recharged. Not very convenient. After about a month, it stopped taking a charge or turning on completely. I threw it away today, as I can no longer return it. Lesson learned.

The Bluetooth Cassette does its job. Honestly, its not bad. The only caveat is that you have to keep up with charging or else it'll die randomly, and plugging it in is not a simple task when driving, so effectively you're left without music until you stop. Otherwise, its a nice gadget. The best thing about it is that I haven't experienced any horror stories with it completely not working, as some other people have. I've had it for over a month now, and I'm still happy with it.

Works great when it works, but battery life is only a couple hours and when around 30% it makes a constant beeping reminder to charge basically making it practically dead at 30% with how unbearable the beeping gets.

I like this device because it does work well for my old factory radio. The sound quality is good and works well with my google pixel phone. I am also able to use google assistant with this adaptor. For people that want to keep using their old factory radios that have a cassette player, this will really surprise you. Hands-free calling works very well with this product as well. I rate it at 4 stars because I wish this product didn't have to be charged.

Works well with my 2003 Toyota Tacoma truck. I can listen to my music and make phone calles
