I purchased this eye piece along with the Kowa TS 663 spotting scope.
I have owned a Leupold 25 X spotting scope for about 25 years. I recently took up long range Hi Power rifle shooting and needed an angled eyepiece, more magnification and clarity to see bullet holes and shot markers at ranges past 200 yards.
I really like the angled eyepiece for prone shooting and objects are still clear when there is no mirage at 60 X magnification.
The Kowa is four times the price I paid for the Leupold. Is it four times better than the Leupold? There is no way for me tell how clear objects would be at 60 X in the Leupold.
Setting the Kowa at 25 X and viewing the same objects at the same time, I am still trying to convince myself that there is an optic advantage other than the ability to magnify up to 60X and the angled eyepiece which I desperately needed.
My suggestion to prospective buyers is to do a lot of research, more than I did.
You may find something that allows you to see what you expect at considerable less money.
