Im usually not an on-stage guy cause I know a lot of their stuff really isn't up to par (I've had on-stage saxophone stands break on me before while my horn was on it.. but I'm really surprised about these. I went to my local store cause I needed to buy some mic stands for an upcoming session that weekend and there were no k&m's, so I was directed to these and color me impressed. They're HEAVY, and in a very good way. I'm not worried my mics are gonna fall even with the boom fully extended, and even walking near them there isn't a lot of movement in the stands themselves. Only giving them 4 stars because one of them I couldn't collapse all three way because the bottom joint was stuck, but with a little force I was able to get it to move and now it works perfectly fine, also I haven't used them a whole lot since I got them as I got busy with school so I'm not sure how well they'd hold up to regular use with heavier microphones. For my needs though they do the job perfectly fine and I'm very happy with them.
