I use a similar product, Optima2000, and they have their goods and not so goods. If they are mounted close to the boreline you can pick the reticle up rather quickly, like on my 22/45. But if you have to mount them on top of a weaver rail, you may spend some time searching for the dot. I went back to an UltraDot on my Bisley because it is quicker on target in that application.
