I have one as well. There are much better scopes that give a much better image, but they're quite a bit more expensive so at this price, the Teslong is a great value. Interpreting what you see is another matter, there are multiple threads discussing whether something is a carbon ring or not, whether gunsmiths should be challenged when scratches are seen in the chamber, etc., so interpreting what you'll see takes some effort and experience with the thing. I think most of us believe that more information is usually better, however.
