As a tool, it does the job well. It does exactly what it says it will do, which is give a more "studio" sounding room. With the help of some acoustic treatment behind where you stand (for now I've just got 2 very dense and thick foam matresses on the wall) it allows me to record a very usable sound in a 5m x 4m room that not at all acoustically treated.
My strife with this product is that it isn't the most well built of things. In fact I am finding it a little appalling. The logo is slightly dented on one corner (which just annoys me but doesn't affect the sound, I like things to look perfect and I'm sure I'm not the only one), the small glued on logo isn't really straight (again just annoying), the tightening bolts don't tighten enough to make it completely stable (one of the bolts actually snapped whilst I was tightening it to try and keep it secure), and the whole clamping structure just seems a little fiddly to me, I'm sure there is a much better way of doing it. The box had not been damaged in anyway during transport so I can tell that these faults are obviously from the factory.
Although I don't like the quality of the clamp or the bolts which seems to made of a metal/plastic alloy, I do recommend getting this if your room has terrible acoustics, as it is the only way to help without splashing out thousands and thousands on acoustic treatment, the cheaper versions made of foam really don't help at all. Having said that, SE Electronics now has a new one called Space which is double the price, but HOPEFULLY is double as effective and much better built... but that's just me being hopeful!
