Used this company twice and both times I have found the overall experience satisfactory. They must be a fairly large concern, lots of customer service but difficult to speak to a technician which is really what Id like to do dealing with technical issues. Found quite expensive but nonetheless ultimately reliable . Didn't like when I had ECU replaced it arrived back with a sticker saying warranty no longer applied so it seems like the lifetime guarantee for faulty workmanship only lasts once !

I only heard good reviews about them so far. Good to know about the warranty bit.
