I bought this item several months ago and I have to say that I've been quite impressed, It's very easy to use and once set up works fine. It is relatively easy to use as you basically look through the glass window at the night sky and your scope should see what it sees, assuming that you have set it up correctly. Overall a decent finder scope.
