I pretty much echo Michelle S. review except not as generous on the star count. I try and donate every 8-12 weeks but their f/u can drive you nuts. Way too much soliciting!
I also don't like the open air blood letting with all the personal conversation going on. I prefer my privacy to remain, well . . . private. We look like a herd of cows rounded up for their evening milking. I think they can do better.
