I have the angled version. No complaints here. Image quality is great and low-light performance is pretty good in my opinion.
I really like the huge focusing ring. Makes it very easy to adjust quickly and it comes in handy when you're wearing gloves. I also appreciate the rotating tripod ring. At the range when spotting, I can swing the eyepiece to a horizontal position so that I can look through it without having to stand up.
I have taken it on several archery backpack hunts and it has endured the torture I've put it through so far. Of course, I'm sure you already know about the fantastic warranty.
