You can easily spend over £100 on a 10 stop filter but thought I would try one of these as long exposures are not something I do a lot of. Very pleasantly surprised... I tried it out this morning and it gave me 10 stops no problem, probably a little closer to 11 stops. It has very little in the way of a colour cast and what was apparent was easily rectified in photoshop (as you would for any ND filter). For the price, it is a contender for any camera bag.
