I have had 2 Wonder Optics (WOTAC) scopes. I liked them, they were very close in design and quality of SS brand from SWFA...I have one of those also. I really liked the WOTAC reticle. I had a problem with first one after I had had it about a year, started fogging internally and I sent it back and the owner exchanged and upgraded it to the next model for free. The turret was slightly mushy on the first one, the replacement one was good.
