I bought this 58mm CLP & hood for my Canon EOS 18-55mm lens because of the low price and so far have installed the UV filter and hood. The jam ring on the hood is not very tight which means the hood if knocked can twist out of alignment a little too easily for my liking. I can usually catch it and twist it back before it affects pictures since it shows on the outside of the frame in the viewfinder but it is a minor inconvenience. If you try to tighten the ring it skips over the thread at a low torque so cannot be tightened hard. I guess I got the quality I paid for.
