Rated 5 out of 5 by from Better than most. You have to be a proper sausage fingers to over tighten or snap these. I however did break one but I was trying to cut it down to fit a tight spot. Solid terminals. At the end of the day if your messing about with a ring main so you want to save 10p and risk it over heating or poping out and shorting????

Rated 3 out of 5 by from Bog standard terminal box These boxes can have their faults but are OK if used carefully. I use them carefully and have not experienced problems. The price is good.

Rated 4 out of 5 by from Mostly good! Generally robust - one faulty jb to be returned because one female thread was too short. Screw was jammed and very difficult to release and when retightened left too much of a gap to clamp the cable.

Rated 5 out of 5 by from Decent Jb for a change Having been in the electrical trade for over 30 year's I've seen products change and sadly not always for the better. A lot of Jb,s these days are cramped with small terminals, this one has plenty of room and good solid terminal screws. You can join a 6mm twin and earth no problem.

Rated 1 out of 5 by from Bad batch... They do look the part. Terminal grub screws are the main problem, the screwdriver slot it poorly formed, not deep enough, too wide. So bad I couldn't back the grub screws out. Tightening was too vague. Terminals also push out the back unless the box is fixed before wiring. Took them back, and used Wagobox and 222 connectors I already had.

Rated 1 out of 5 by from Very Bad Junction Boxes DO NOT PURCHASE THESE JB . The screw terminals are zinc coated steel , not Brass they will start to corrode very quickly , I have fitted some of these in my Double Garage about 6 months back , ,needed to take another feed from one opened up ( had been sealed outside with siicone ) screw had corrosion on them , so I am looking at trying to get some Brass screws now to replace the steel ones ( 5x3 ) or will have to replace the whole JB's .
