I tried out my Mamba Lite for the first time today.
The optics are good, and the reticle is very nice to use, much better than the usual lines of dots. I was only shooting at 20 odd yards today, but I'm looking forward to using the ret at other distances.

I don't like the attached covers much. Nothing wrong with them as such, but I did find the rear one gets in the way a bit and catches on my clothing when loading my TX. Probably pilot error as it's a new feature to me, but I prefer removeable covers on elastic bands. Any reticle focus adjustment means the rear cover turns as well. You can set the cover to any position you want, but if lending the rifle to someone else, the cover could end up in an inconvenient position for that person.

The mag adjustment needs a firm twist, but nowhere near as firm a twist as my BSA needs. Some people have said it's too stiff, but I thought it was ok, and it would loosen up with use anyway.

The big let down for me were the small turrets. I wouldn't fancy adjusting them in the winter with cold fingers.
Also there aren't any positive clicks when adjusting them. There is a faint click, but you can't feel it when turning the dials, and adjustment feels vague and mushy. Any time I made an adjustment, I had to hold my ear near the turret and listen for the click to tell me when to stop turning. My 50 quid BSA scope is dead easy to set as it has larger turrets, and you can feel and hear the clicks. With the Mamba Lite it's hard to tell if you've stopped on a click, and you get the thought that the setting might slip one way or the other.
Not having much turret to get hold of also makes it seem stiffer than it probably is. I think the inset circle with the markings on could look nicer, as they each have a slit in them for some reason.

This is the first scope I've had with a side wheel focus, and that works very well. It turns easily enough, and has a quality feel when using it. I don't think there's any need for a larger wheel on the side as this one seems just right. The distance indicator marks seem to be accurate as it read just over 20 yards which matched with what I'd roughly paced out.

Overall build quality is very good, and the whole scope feels nice and solid.

The only thing that would put me off buying another one is the turrets. I've zeroed my BSA in for different distances loads of times, but I'm not sure I'd want to set this one up again, it really was a chore.

With larger turrets, and a more positive click index I'd recommend the Mamba Lite to anyone looking at scopes in this price range. The reticle is worth 10/10 on its own.
