one lense put in backwards

One of the lenses was put in backwards so one pair was useless. I would've loved them otherwise. Probably wouldn't recommend to a friend.

they are hard to clean and I noticed one lens is much stronger than the other.  They also advertised only one strength.

this was a Christmas gift for my son. He's just putting it together with Spring coming. But there's something on the inner lense that we can't get to.  How do I return for a new one?

Arrived with something wrong with one of the arms, and the price went down $8 to boot. Not sure if i should return or not. The arm is stuck sticking out when not in use* Looking in the mirror i also notice that one lens comes all the way to the bridhe of my nose, while the other sits normally??/

Great little lenses. Turn counter clockwise to separate the wide/macro lenses.

It has to be positioned carefully to work right and it slides up and down the lens tube, which affects how they close.  They're cheap, so I probably won't return them, but will be replacing them asap. For the record, I don't like them.

Pretty neat set of lenses. I bumped the fisheye lens with my thumb while I was messing around with it and it's a little warped now, but it still looks interesting.

the left lens on one of the three pair had a small defect in the lens. Kind of irritating, but not worth the hassle of returning or exchanging for $12

One side of the stereoscope is not put together properly.  I can use it, but it is difficult to open and shut.

These arrived with one of the lenses popped out. I could not get it back in. It was not worth the gamble to have to send these back. This was a regrettable purchase. The packaging was not damaged at all. My guess is that they went into the box that way.

I bought 3, one of the scope and holographic sight had some pretty bad pincushion distortion. I've got it set aside as a 'worst case' backup scope.

I had to take the parts apart and use part of the ones that I took off. the direction of travel was backwards.

I was very disappointed that only one pair had mirrored lenses. I would order more however the mirror issue is stopping me from doing so.

When i received i rhought the lens looked odd with the cut outs on the top of the lens. Thinking when i snapped them in the cut outs would be hidden. NOPE. Returned

I knew these were cheap glasses but I expected  them to be in one piece when I received them. When I took them out of the package one of my lenses were popped out.

2 of the lenses attach to each other and don't stay together.  Hard to fit over lense of the camera.

I liked them, until one lens was scratched right in the middle making them impossible to see out of. I looked to return, but I missed the window by 1 day! So, 26.00 down the tubes
