I’m looking at smart top modules. I see there is a site called Ec-modules online. They seem to do the same as a smart top module but a bit cheaper. Has anyone fitted one of these?
Looks very familiar to me, I'm sure that's re-branded, but I'm sure you'll know for sure

I got knowledge about 2 modules sufferring on instabilities after plenty of years, not representative.
Andy always offers support and a module check even after warranty end.
