I have been using K&M stands in my studio for years and needs to replace a few stands which had got broken. These were my first choice, they are well build with everything you would expect from a K&M stand. Sturdy and able to handle any mic i have out on them. Probably not recommended to use fully extended with a heavy mic for example on drum over heads.
The only negative point i have is the rotating mechanism is a bit gimmicky, as it controls both the extensions and the angle of the boom, makes it a bit awkward to position mic in exact locations as loosening it cause both angle and extension to change. Overall a decent stand for the price!
I bought six of these and these inexpensive microphone stands are very good friends of mine on a stage. It's easy to handle with single screw to tighten or loose the boom pole in pan and tilt positions. It's lightweight at less than 3 kg, but feels sturdy. Feet are long enough to support even my heavier microphones (AKG C3000 + pop filter) with boom fully extended. My only concern is that the black coating might get scratched if not taken care while transporting. Not really a flaw but rather something to have in mind. Good buy, no regrets.
