It is a very high reach microphone boom stand. When I say very high, it can go over 4.5m high. This is ideal for overheads, recording a choir, a brass ensemble and various other applications. It has a down side though : it is VERY heavy too.
Mine fell once and it had the effect of a sledgehammer. It fell on laminate flooring and left a big round mark on it. Its own weight smashed plastic parts in the fall. The weight is one issue and because of this, it makes it awkward to handle too. Allow some room to manoeuvre in any rooms/ studio and also in your car.
Build quality is very good and the weight makes is feel very reliable but ironically, is letting itself down at the same time.
The price is great for what it is, I would recommend it and I might buy more in the future.
