Yes, I fly with them currently.
Have experience flying their Pa28 Cadet, DA40's and C172.
The a/c are of good quality, compared to other a/c around the airfield (I've had experience), the DA40's/DA42's generally (all schools) have been known to break down a bit with their ECU's etc, but these a/c are used quite a bit. Might be worth checking if they have more than x1 DA42, I don't think they have, so worth noting when it comes to doing your IR, for any back-up a/c to use. Their C172 is great
Saying that, I'm considering at some point to convert to the glass, to decide if it's what I want for the IR. Their DA40's are both analogue and glass and it doesn't cost much to convert to glass any how.
I've had a trip as a passenger in their DA42 to France the other year, a fun experience and I checked out their new DA42 sim the other month.... but not as good as the real thing, graphics are quite basic lol, but at the end of the day, it's for sim instrumentation practice and not really to do with graphics.
I'm not sure where I'll be doing my CPL/ME/IR, I might do it at Shoreham, either Flying Time or another, but I'm more inclind to go some where which has more of a proven record with the CPL/IR, this school is quite new to it still and I'm thinking more towards that of an international airport, to blend in with the commercial traffic - each to their own.
It depends what you want, but for me, it's a professional qualification, costs a lot too, so I want to ensure that all my boxes are ticked when I make my decision ie. being in a professional environment.
I'm considering BCFT, PAT, Bristol etc, but this is a few years away yet. I'm going to hang fire until I get those ratings out of the way.
