I bought 2 of these the last time they were on woot. They work great in my cars. Like the idea that it has a solar charging option. Yes, it even charges in Vancouver, WA. woot woot!!
I have one of these. It works great. The wife could never hear me in my loud car using a regular bluetooth headset. We have no trouble hearing each other now, on my long commute.
If it comes back up I’ll be buying another for her car.
