Upgrade telescopes for 2nd gen alpha loupes.
Telescopes only (No frame).
I have tried them and have compared them. To be honest had a hard time just the first day but i took my time and now i can totally say that for that mmoney they are moooore that great.I have the 3.5 and the 5 hd loupes and the light. in that price range 10 out of 10 .overal a hard 8 .almost perfect. waiting on 6x or .If they were individualy adjusted 100% they would be one of the best out there.But i had to choose i would buy the again no doubt.
