My brother mentioned his interest in one of these. He is a casual user of his scope. Often times he's watching eagle nests. Anyone have experience with lower end models of these devices? I see mixed reviews. I don't want to break the bank but I also don't want a POS. Thanks.

I bought one but I think I need a better spotting scope to use it on, the picture was not as clear as I’d like. Plus, my spotting scope is wobbly. It was the SME brand, if you are interested in a once used model let me know.
