Very good value. The set of adapter rings is helpful. Of course there is a color temperature shift. ND filters pull to blue when compared to Cokin P154. Use the RAW format and the problem is minor. The plastic filter door is a little "cheap". The size of Cokin filters is nothing greater than those supplied in the kit, but if the Cokin filters are placed in the last slot (away from the lens) of the kit adequately filter out not only all their slides . In short a good entry-level product.
