After searching multiple references filters I decided for this model, taking into account the price and included filters. Compared to other references / sellers, here a small storage pouch is included. First practice it nevertheless has the drawback of having a coating like "velvet" synthetic poor who tend to leave some dust on the filters, which is not very sensible for this type of product, or even more unfortunate. Nevertheless it comes to the main filters in themselves. Size 58mm, they fit perfectly on my IS II Canon lenses (18-55mm and 55-250mm in). The ring is metallic, a qualitative element when handled. The quality of glass also appear at the rendezvous, a fault on one of the filters that I received demonstrated, there is a real glass. My polarizing filter so having a defect (small chip on the edge, at the limit of metal ring), I have not been able to realize it will be visible and annoying during the shooting, the conditions of use This filter and my region do not allow me now. The UV filter when with him essentially filled the position for which I wished to acquire it: protecting and preserving my goals. The installation was carried out without problems, disassembly gives a little more sweat because the thread holds very well (too perhaps?) And I recommend suddenly move the lens to manual mode for especially not force the autofocus mechanism of the objective (of course always hold the manual focus ring). The value for money is still there, I regret that the protective sleeve is not in single textile material not to put dust sought to avoid this type of product and of course the small defect of the polarizing filter, d where "only" 3 stars for me.
