This is a very nice piece of kit, small in size suitable for Refractors. You get a choice of red or green reticles with different brightness levels. Also 4 choices of reticle shapes.

The only drawback is that setting up was very fiddly. You need a tiny Allen Key (which I have since lost) to unlock the adjusters. This is found in a very small hole on the right-hand side (viewing from the rear). The instructions are wrong in regards to the procedure for aligning. When you have finished adjusting then re-tighten this.

You then need another different size Allen Key to adjust the reticle position (On the top and left hand side). This was rather frustrating as left/right position hardly moved, but up/down seemed to work ok.

The battery was missing from mine, that was another reason for the reduced star rating.

However after all that, I do really like it and I am really enjoying it. I just thought the Telrad (which is my favourite finder) would look a bit silly on a 80mm Refractor.

So if you have some patience then I would recommend this product.
