Disclaimer: I am a casual shooter and I am definitely not a glass snob. Many others have their own personal expectations when it comes to optics, and no one can fault them for those. But in my casual, non-competitive and normally close-in shooting (90% within 50 yards), I do not really push any glass to its limits, and may not really critically examine or review glass as well as others.
I have the both of the Optisan compact optics - CP 10x32 and CP 3-12x32. They were both purchased from Trenier. The 10x32 has been on some other guns, but it currently resides on a newly acquired S510 Carbine. The 3-12x32 is currently not mounted, but was most recently on a now-sold Impact Compact (and will be going back onto a different Impact Compact).
I have always found Optisan scopes to be light, generally compact, bright & clear, and fully functional for my needs. Their reticles are clear and sharp, and are not overweight. I haven't owned them for more than say 6 months, they generally get light duty from me, and I have not had any issues with any of them.
While I like the 10x32, for the extra money (and if available) I prefer the 3-12. Just more flexibility for me, without a significant weight or size penalty. I am using the 10x on the 510 Carbine because I wanted the light & compact form factor, and this gun will likely be used from 35 yards on in. I do like magnification - my 62 yo eyes have never been all that great, even when younger.
I recall that Yodoyle (remember him?) had some stories (fancy that) regarding Optisan in general. He thought that they were cr@p optically, and cr@p as a company. He told me that the company attempted to dodge warranty claims which either he or his friends tried to make regarding their scopes. He also mentioned that he didn't think it was right that the warranty was not transferable from the original purchaser. Take that for whatever it is.
I like the Optisan CP scopes, and would purchase another 3-12 tomorrow if I had the need.
