Thor HD 640 50 or 100mm

Anybody have any legitimate time with these scopes? I'm weary of the bugs but I've got a line on one at a decent price. Any reviews, info, or feedback would be appreciated.

The picture looked really good, when it worked. Not even sure how to describe it, but I will do my best. Sometimes the scope would be completely white out. Leave it on and 5 minutes later it had a good picture changing nothing. Seemed like it worked less than it worked.

So pretty buggy I guess. Did you wind up sending it back?

I might have gotten a bad egg. It worked fine the first night out with it. Then that started happening. They are on to something with everything being on board. It is nice to not have to deal with an external DVR and cabling. If more have the same issue, hopefully its a software issue and they get it worked out.

Yes it went back.
