OK but certainly not great for the price.Rather too much CA (even for an inexpensive scope) when backlit. But not so bad the rest of the time. ER is not great. Sharpness is not at the limit of my eye.FOV and AFOV is not bad. Rather better than the zoom version I suspect.Compared with say the Opticron MM 25x60 it is rather worse across the board (less sharp, less contrast, more CA). And much worse than say the Vortex/Stokes Sandpiper.Still it is very lightweight and compact (rather like half a 50mm porro bin)For a cheap and lightweight scope it can be better than nothing but it's not a standout. Perhaps best used on a Stedistock or similar cheap shoulder mount for walking use though it does sit rather far away from the eye on the closest Stedistock mounting point.I have to use it more in the field to get a feel for it. Sp far the one task I used it for (on a very short SLIK tripod) was viewing a backlit Red-tailed Hawk which was perhaps better done in my 8x ED bins <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" />.More as I use it.</blockquote>
