Hope they last longer than the Lemforders on there at the moment as they have lasted less than 2 years or 45k...maybe I being optimistic but don't remember replacing them every 2 years before
It appeared that ECP were, a few years ago, selling Lemforder stuff likely sourced from dodgy sources... ...as Lemforder they weren't. I suspect if there were some fakes going around, all the usual places that this membership uses, such as ebay, would be full of them.
The way I look at it is £20 for a cheap set that *might* last the 1yr warranty period, or £25 for a set likely to last way beyond 5yrs...
...to me, the latter sounds infinitely sensible, cheaper and less hassle. But I'm just the stupid kid from the local comprehensive.
