This is an excellent product. It replaces a unit that broke after some time. The old one had the battery door open and needed to be recharged. You need two AAA batteries. It's lightweight - good to travel with. Batteries can last 2-3 weeks between charging. All in all I'm very satisfied with performance - no complaints.

Ex Output:
Good Review

Ex Input:
This does the job, and it works well. The only problem is that if you use your phone after it's fully charged, which takes quite a while, it'll kill this power supply pretty quick. There was also an internal short in my unit after several months, leading me to believe I got a lemon. As others have noted, their customer service is excellent, but they will not honor warranty. What we ended up doing at our local electronics store for a replacement charger wasn't bad either.

Bad review

I have had my system for about a month now and love it. Great sound quality with an easy setup. My favorite feature is the headphone jack on either side of receiver. The only drawback that i see so far is: every once in awhile there can be little static/interference. Overall though great buy.
