Good clip, but let down by plastic insert

I always love the K&M stands and accessories and highly recommend them to others. I purchased some of the K&M microphone stands recently and thought these would be good too.

This clip is ideal to hold normal microphones such as the Shure SM58/ SM57 etc. The clip holds the microphones well and they don't slip out at all. The build quality is generally good, although some downsides I have found. Firstly, the insert to change the size of the clip at the bottom is only a plastic screw - seems a little cheap considering the price and usual quality from K&M. Second issue I have had is that the nut and bolt to adjust the angle can work itself loose quite easily, and I have lost a couple on stage - never to be seen again!!
