Yes, I had an Elecsol changed by Chelston at 13 months, with only a little fuss. I think my conclusion is to buy from a good local dealer not from a large internet 'specialist' at a lower prices. Only thing is you get much less choice. At the time Chelston only did Elecsol, but they had an offer so it was a good price. Highbridge, another local-ish dealer only seem to have an own brand, so your choice is limited.
