K&M advertise this as a table clamp, but I do not see how this can ever be used as a table clamp. The boom arm is too long for this to be practical. It does have that use, but this is definitely more at home as a serious recording clamp which will see its main use as an extra telescopic boom for microphone stands.
I bought this to record the snare bottom. It is absolutely perfect when combined with a K&M 25900. Some people use rim mounts, but I think that the less microphones attached to drum hardware when recording, the better.
It rotates 360 degrees. Is stable and doesn't droop with a SM57/C451. The clamp fastens tight so doesn't slide. It matches the quality of other K&M products.
It is slightly more expensive than I would like for what is basically a telescopic boom arm attached to a clamp, but something like this really makes recording easier so is worth the little extra money spent.
It can be used for many other things, like adding a second telescopic boom to a single mic stand for stereo recording. You could even clamp it to doors or pipes for room recording if you run out of mic stands. The clamp opens very wide which makes this very versatile and it works on both flat and round surfaces.
I am on a very tight budget, try no budget at all, so I am very picky about what I spend my money on. I am completely happy with this purchase and I will use this for a long time to come.
