Rated 3 out of 5 by from Brittle but Screwfix replace I tried working with this knowing the reviews but couldn't find anything other than this in stock all over town so i got it. It broke when trying to straighten in on the meter board. The replacement I got also had a crack on the slot in part so I'm hoping nobody touches the thing until a rewire is due on the property. Good thing is it's double pole so it's slightly neater.

Rated 4 out of 5 by from Connector block Bought this to connect two 25 mm tails together during a consumer unit change and found these make a rearly good job of it.Have two connector blocks with heavy duty screws that you can apply good pressure to.

Rated 5 out of 5 by from Good block feels brittle Excellent block, used for supplying 2 consumer units with 25mm tails- note that screws need to be backed right out to accomodate 25mm tails ( i removed screws completely to ensure i could see that the copper was fully seated in both screw holes then re-inserted screws very tight as I was paranoid they would drop out.) Had no issues
