It's pretty much the only choice.
Pros:Strong Construction,Compact
Cons: Comments:This is pretty much the only choice for reticle eyepieces and for finder scopes. And it is only available here. I did purchase another brand a while back that had a flashing feature but it was big, bulky, and broke after first use.
Bottom Line: Would you recommend this item? Yes
It would be nice for these things to turn off automatically after a few hours of non use. I just can't seem to remember to turn them off and I'm always replacing batteries.This review was provided courtesy of AgenaAstro.com
