The multi-toned light is the best feature. Having to transition from being around bright sunlight to needing a dimmer yellowish light through the day is extremely helpful. The flexible neck has a slot to help hide the wire from the light. The piece where the light attaches to the flexible neck could be better, it’s a tab that slides into a slot but could be a clip or a latch that could secure it firmly for my own piece of mind. Took a little tinkering around with to position the neck to the way that I want cause the light itself was a little bit heavier than I thought but overall works very well and stays put but I wouldn’t recommend always moving it around as it seems cumbersome to get it back to the way it was.

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

Bought it shortly after buying a Gopro and a knockoff version as well. The accessories fit perfectly for both and I was amazed by the quality of the mounts. Compared to the knockoff's mounts, these were sturdy and didn't budge no matter what I did. Would definitely recommend, if not for the price then for the quality of the accessories itself.

The Price is too high compared to all other devices ,but the purpose is as same as all , got one drive cloud for 4 years free subscription.

I use this product for working on my computer. Product is light and comfortable in my ear…great sound quality…

So far this circular polarizer works with excellent results.
