They look pretty useful, how big are they? And more importantly how
much space do you need on the edge to be able to lift the panel off?
Or is there some magic release mechanism (I guess not for the price!).

One sort presses on, rather than dropping on, so shouldn't need much
edge clearance, but I haven't used them, just noticed them and mentally
stored them for later.

I just used s/s socket cap screws on the tiled access panel I've done,
as it went with the look anyway. Oh and I siliconed the gap and if I
ever need to access, I'll cut it.
