The filters are of decent quality. This kit PERMER to have different filters available in case. The polarizing filter is quite effective, Neutral filter can protect the lens of the case. For other filters, I do not have them tested in their conditions of use, so I can not give an opinion. The small bag is convenient to store it all, but it lacks a compartment for the support which suddenly cruising. Otherwise, the shipment was pretty quick, deadlines were met.
