Great for adjusting ND intensity on the fly, easy to use and remove when not needed. Took it with me to download festival and survived a number of moshpits and being flung about and came out without a scratch.

Perfect as advertised. Easily snaps on and works flawlessly. Much easier with the rotating stops than having to carry different filters for different occasions.

Great product for the price crystal clear in my final edit , fits nice and snug I use it with my motorbike and it hasn’t come loose .

Very good. Don't use them at their max you get mental vignette... how ever check footage on your phone and give them a spin to put it in a less obnoxious place as there's 2 very obvious shadow areas with hardly any colour. Normal sunny day in uk and u can get away with the n32 on its lowest setting an gives excellent results instead of maxing your nd16. Also delivery was fast and well packed. If it wasn't for the crazy vignette that ruined my first motovlog I woulda given 5 star

This variable ND filter is completely unusable due to extremely severe cross-polarisation. As you can see in the example image, the corners become completely black, making the image unusable. This doesn't just occur at the extreme end of the ND range – it's present from the start and becomes increasingly severe throughout the range. Returned for a refund.

Almost unusable at times due to purple/blue fringing around the edge of the frame. Will be returning!

THE BEST!! I had a set of ND and it was a pain to keep changing them as the lighting changes, this one is so easy to attach (you won’t lose the waterproof situation but I haven’t tried it underwater yet so idk if it stays on)! The price was great as well considering that I paid more for a set of 4 before!

Lovely set of filters that do their job to perfection. They are a bit big, bit that is personal preference, sand I prefer them big. Really good quality, and I am fan of how they attach on to the action cams personally, very simple and easy.

Very happy with the quality, very impressed with everything.

Great quality filter with no color cast and snug fit. Great value for the price

Offert à un photographe pro en devenir. Cadeau très apprécié, je recommande +++

Excellent pour le motion blur

Se serre tres bien a l’objectif

Prodotto conforme alla descrizione, buona qualità e consegna puntuale. Soddisfatta dell’acquisto.

Il filtro è arrivato senza problemi, imballaggio molto bello e ben curato. Fornita una scatola con l’imbottitura interna per stabilizzare il filtro. Viene fornito anche un panno in microfibra per pulire l’obiettivo prima dell’utilizzo.

Viste le premesse dell’imballaggio mi aspettavo un gran prodotto che fosse in linea con le aspettative create. Purtroppo invece mi sono dovuto ricredere dato che una volta applicato il filtro l’effetto della lente avviene solo in alcuni punti della visuale della telecamera, rendendo le riprese inutilizzabili e brutte da guardare.

Veramente un peccato perché prometteva bene. Non compratelo
