[General Question?] Opinions of Coolsat 7100 PVR

I'm thinking about getting one of these. I don't see any reviews from anyone, and I was wondering if anybody has one and what do you think of it. I also noticed that there are a lot of fixes, does this one go down a lot or just some issues that were being addressed?

Being computer/electronics challenged, are the PVR functions easy to use. Thanks for any input you can provide.
Sincerely,

Well it's like all the others when it new ecm all receivers go down., like right now.......
