For the price, it is really good.However, it does not turn smoothly and therefore may unscrew the polariser in the process, which is why I remove one star.Also, the mount is quite big and could be a bit smaller. But at this price, it is difficult to complain.Thanks

The lock is we'll made and the app is great. I easily create timed codes for my guests.

Bon prodotto per qualità prezzo, ottimo starter experience con una action cam.

Absolutely fantastic quality lens, great color. Nearly useless stand/mount. Come on Logitech...get your act together. I need a clip so it can be clipped onto the top of my monitor or laptop screen! Make the mechanical engineers sit at the knee of the optical engineers and learn a little something about customer usability. To prospective buyers...if you're a DIYer (Do It Yourselfer), take the mount off and throw it away and make your own clip.

Overall this filter is very nice, though the only thing that made me drop a star is due to the fact the actual grip for the filter that lets you unscrew it from the lens is so tiny and awkward to use to the point where depending on how much I used the filter I'd have to use an elastic band to add grip to twist the filter off as it was shredding my nails trying to twist it after trying to unscrew it normally.Otherwise I love the filter, just I feel I might not use it as often as my smaller lens ones due to that issue.

Great desk lamp - easy to set up and love the multi choice brightness.
