First, I want to say that when you order in England, you need a delivery month for a simple envelope !! I bought these clips, two months ago and a storage case. In seeking housing for storing these clips, I asked myself the question: why did not you bought the pliers to other diameters? At the time the other diameters did not exist on the web, or I have not found. If you look closer the product, although I filters in aluminum, iron, alloys of different short, I have no concern disassembly by hand. Knowing also that when the filter is mounted on the lens, the system is not easy to use. Also when there is a sun visor, which is inaccessible to unscrew using pliers.
In conclusion, I have new equipment, it is perhaps for this reason that I do not see the point. Anyway that's my opinion and advice to users who are new to the photo not to buy pliers, despite its low price. It is a fact that the picture accessories are expensive and you tend to buy to buy. In reflecting more closely, just use two plumbing necklaces, taking care to protect the filters with a rubber band, and voila. I think the problem must be on the adapter ring to move a filter from 67 to 58 mm for example if multiple rings. As for me, I do not have this problem because I use a single adapter ring.
