I think its hit or miss with those scopes, I came across a thread on here last night and they had huge success with one and the pics looked amazing, makes you wanna go strait out and buy one. What i think is happening maybe is that there are few manufactures in china making the same thing but it seem only one does what it say on the tin (like some of the LED grow lights). Now which one to get is a good guess as typically with china copy's no manufactures put there name on. I think its the jewelers loupe to be safe
