I've now been using this scope for several years. It is compact, solid, but smaller and lighter than the TSN 883, very well made and optically superb. While I do call it "compact" it is by no means small, just smaller than its big brother and a few other 80mm plus scopes. I use the 30X fixed eyepiece and the image quality is all you could hope for. Brightness and image quality are remarkable. "Crystal clear" and "razor sharp" are very much overused phrases when people talk about optics, but in this case they truly do apply. It's an excellent spotting scope for birding (which I suspect is what most purchasers will use it for), and it sheds half a pound compared to the 883.My preference in spotting scopes has always been for a fixed eyepiece in the 30X range, which gives you adequate magnification and a relatively wide field of view (typically much wider than a zoom even set at 20X). In addition, my experience has been that fixed eyepieces are always superior optically to zooms, though zooms certainly do have some advantages. There will be a few distant birds that you will miss without a zoom, but IMO the trade off is worth it. I highly recommend this product.
