"These are good quality items at a good price. I've come across 5A boxes before which are far too small to work with, and terminals you can't get more than 2 wires into. You wouldn't want these to be any smaller, but they are large enough to get 4 x 1.5mm twin and earth cables in, and connected to the terminals."
"Well made product at a great price. Like all electrical things they are a bit fiddly if you're trying to get the maximum of 4 cables in but once they're in, they stay there with properly fitting grub screws."
"The slots in and the terminal screws themselves are far too small. I have just used 12 of these and 3 Hager, Hager win all hands down, but they are a little dearer, but you only get what you pay for."
"Need these size junction boxes to fit in down-light holes. Boxes are far too shallow you will have a lot of trouble fitting in more than 2 cables. I would not recommend these for making off loop in/loop out + a switch line and load cables, they just don't fit. Boxes need to be deeper so the terminals inside can be deeper. Only recommend for 2 cables max."
"Bought these to do some downlights, didn't have Crabtree or Hager. Bought 10 and after the first one was depressed. Poor terminal size, poor screw, too tight for space and found almost impossible to connect , 3 x 1.5mm cables into and then getting lid on was yet another challenge. Take advice, buy better make, quality and make the job easier as after 10 , you'll never buy again no matter how cheap."
