It works great for what I need it but the battery does not last for months like advertised. I have to recharge it about every 3 weeks.

Great quality with an affordable price! It’s super easy to use too! You just remove the lens cover and click it on! It’s literally a two second set up. Many others who saw me using this have asked me for the link!

Used it right out of the box and it was amazing! Great picture and easy to use.

I have been using this filter primarily to get rid of glare in my webcam setup so my requirements may not be as stringent as for more classical applications. Compared to a Nikon filter I have (of a different size, for a different lens), the polarization effect is a bit lower on the Tiffen, and it also lets through more light. Contrary to some comparisons I've seen online though, the Tiffen for me produces a warmer picture than the Nikon.
