Pros: Update on my prior review: The seller was very helpful, and paid to exchange for a second unit...which also didn't work on my Galaxy S3. They then discovered that in fact this unit doesn't work with the S3, so they're refunding my money and they've changed this listing to reflect the fact that it's only for the S2. So the unit may work great if you have a Samsung Galaxy S2...I have no way of knowing. But I'll give 5 eggs this time to balance the first review, and because of the responsiveness of the seller.

Cons: None that I know of.

Pros: It has the correct power port such that my normal phone charging cable would plug into it...I heard some of the competing products had a problem with this.

Cons: I hooked it up to both my Samsung 58" plasma HDTV, and to my 27.5" Hanns-G computer monitor, and didn't get a picture on the screen in either case.

Other Thoughts: I chatted with Samsung tech support. They confirmed I'd followed the directions correctly, and then had me reboot my phone to no avail. I politely refused their next step (do a factory reset on my phone, wiping out all my contacts, settings and apps).
