Haven't bought one yet but I have one in the shed (if I can get to it) that I rescued from my sister's shed a while back. She had to get it replaced with a smarter one when she introduced a scheme for her company to pay for home charging... so it should still be working... won't know for sure till I have a car to plug it into though. Failing that I'll either get the one the erm got on Amazon for under 2 ton or maybe the one Screwfix sells for c.4 ton (NI price, no VAT up there on EV power supplies) that has a CT clamp for load balancing... just not sure that I need load balancing, there's not much load to balance when we're asleep!
