In terms of the board itself...
Very strong. Knockouts come out easily. Knockouts on every side is a plus.
The extra space was most welcome as 3 CPC's needed extending.
Enough room above CPC bar for tester clip to nicely bite.
Negative points from my perspective...
One main earth, 2 bonds and 1 per circuit could have left me a little short on the CPC bar. I don't know whether I'm imagining it but think Fuesbox has more capacity than that.
The screws that hold the DIN rail assembly seem to be self drilling/tapping not machined and after removing it all and putting it back I very easily managed to strip the thread on one of them. So had to drill, tap and use a bigger screw. Another time I wouldn't remove it - I'm just used to easily doing this on Fusebox boards.
Finally, being a bit picky but it's not super-easy to see the breaker ratings when the switches are off.
All in all, I'd use one again.
