Very reliable and well made, ideal for frequent use.
Having gone through a huge number of lesser mic stands thanks to lively and busy nightly concerts, our venue were on the lookout for much more durable options (without going to crazy prices, as the best stand in the world won't resist a 15 stone crowd surfer).
An engineer friend from across town spoke highly of these and rightly so. They are in as good condition now as they were when purchased and should we need more stands, our days of cutting corners are open. Whilst these cost fractionally more in the moment, they more than justify it through ease of use and relaibility.
