So much fun to use!
I love to snorkel and was able to attach the camera to my full face mask. I just let it snap away and ended up with quite a few great pictures. I definitely recommend this camera to anyone who likes to take underwater pictures.

Canon T3, works just as expected!
Reduces reflections magically and really does sharpen colors. I definitely recommend this. The only problem is that, if you normally like to manually focus, you have to switch the lens to automatic focus before adjusting the polarizer or else you'll lose your focus! Turning the polarizer will also turn the focus unless it's in the automatic function.*it is very hard to take off your lens though. and you cannot tighten it loosely or else it'll unscrew as you turn the polarizer so you kind of have to tighten it onto your lens all the way

You get what you pay for
Very good for the price, however the tripod came broken. Not bad for price point, and I can fix the tripod with some super glue. Still worth it tbh.

Q
Will the autofocus function of the lens be affected after using the adapter ring?
A
The adapter ring itself does not contain any electronic components, so it will not affect the autofocus function of the lens. 
Q
is there a 72 adapter ring?
A
No! Only:77mm; 67mm; 62mm; 58mm; 55mm and 52mm 
Q
When used with telephoto lens, the adapter ring may be loose
A
That may be caused by the fact that the lens weight is much bigger than camera, If used your telephoto lens with our adapter ring, we suggest to use with a lens bracket and better to shoot on a tripod to increase its stability. 
Q
Too loose/there is gap between lens and adapter ring
A
  1. If there is ever any more than a slight amount of rotational play, you may want to try tightening the lens mount adapter so it will hold the lens tighter to the mount. There are 3 flanges in the middle of the adapter (what the lens locks onto) that are split open slightly, this gap is what gives the tension that holds the lens tight to the body. Over time and with use these gaps decrease in size, no longer pulling the lens tight to the adapter, which allows the lens to move inside the mount more than it should.
  2. To tighten the fit, get a slim metal object (a #1.5 or #2.0 small flat eyeglass screwdriver is ideal) and insert it into the slit to open it up just a little bit (see images below, make sure to do it to all 3 evenly). The more you open the gap, the tighter the lens will be to the adapter; too much and the lens will have a hard time mounting so make sure to do it just a little bit at a time to all 3 flanges evenly, it doesn’t take much at all to get a tight fit.Note: please do not use too much strength, or the shrapnel will be damaged.
 
Q
Can i use this on a 95 mm lens without an adapter ring?
A
It can't not be fixed well with the lens without the adapter ring. you should buy another adapter ring of 95mm size if you want to make this square filter fixed on the lens.
