"I have installed tons of these, they are great value and the LAP face plates actually fit them (the edges line up) perfectly unlike the MK ones! Plenty of knock outs on all sides and a good sized one on the back. Don't screw them back too tight or they will crack like most cheap boxes though."
"Good value boxes that are nicely made and look fine when fitted. Bit hard and brittle so you'll need to be better at nibbling than Peter Rabbit to avoid breakages. Use a small sharp pair of cutters and start in the thick middle part of the breakout just doing a little at a time. Don't try to twist, snap or cut at the sides of the breakout or the box will crack."
"I'm not sure I've had a worse set of pattress boxes! I like to think I'm quite adept at nibbling out the cable entries but one false move and you've had it. I managed to use 4 of 10. Others passed away with the merest hint of overtightening, cracking like a well struck easter egg."
