I have one too (!) and so far, very pleased (roughly 6 months). So much so that I'm thinking of getting a 2nd (my cellar is quite voluminous - but NOT all for workshop use unfortunately).
As someone said above, it's fairly quiet (MUCH quieter than my shop vac for example), has 3 levels (speeds) and a timer (you can set it for 1, 2 or 4 hours, plus continuous of course), all with a hand-held remote control.
Because of low head room in my cellar it's installed VERY close to the ceiling (I made some MS brackets which needed less height than the supplied hooks and chains). In the handbook it gives a certain minimum distance below ceiling for mounting (I forget what it was) and mine is certainly mounted higher up than that (just about room for the power cable to go over the top of the casing, between the machine and the ceiling). So before buying I checked with Record on the phone (very helpful) who saw no big problems with mounting mine right up close to the ceiling, and so far they're right - no problems.
I've removed the outer (in-going) filter a couple of times so far for vacuuming - each time it was pretty full, so it must be doing something!
At the same time I also bought a spare for each of the filters (inner and outer) but haven't needed them yet.
Recommended. Usual disclaimers.
P.S. Just as a matter of interest I bought mine in Germany, although I live in Switzerland (which does have a Record dealer not far away from me). But it was cheaper from Germany than from the Swiss dealer, even allowing for the courier charges and import duty - in other words, I think there are special offers about, probably in UK too.
P.S.S. Not teaching granny to suck eggs but it's an airborne dust filter, NOT an extractor. In other words, if you have a sander for example, as in my case, you also have to arrange separate dust extraction from that - the Record machine will "only" pick up what floats away into the air free from the sander DE.
