Well the included tripod is rubbish. Far too sticky to be useful even at 20x, 60x just doesn't work as you can't frame at all. I've now got it mounted to a £35 camlink tripod which is 100x better and perfectly useable even at 60x. The rotating ring sticks a bit too but not a big deal as I doubt I'd use this a lot or need that level of fine control.
Optically it's surprised me. 20x is clear and has reasonable contrast, giving a pretty good field of view. 60x is noticeably softer and less contrasty, on a photo lens this would be a disaster, on this I really don't think it is. I can still see reasonably fine detail clearly. There is a lot of CA however at 60x, but again not a deal breaker at this price.
The focus control is really nice, smooth and slightly damped. Has pretty fine control so this does mean lots of spinning for long changes.
My main gripe is the focus changes massively as you change magnification, which makes the locate at 20, zoom to 60 awkward. The eye relief also changes from just useable with glases at 20x to no chance at 60x.
Other than that while the objective cover is attached the eyepiece isn't, I can see that going missing pretty fast.
So while no Leica, it's not priced like one either and will certainly be serviceable if you're on a budget.
