I bought a 4 stroke strimmer from yourselves a couple of years ago and had to return it because of starting problems and I thought it was falling apart after a few uses. At least we had a refund. I'm an engineer so I know what is what. We got a strimmer from B&? - 2 stroke, much better quality! Lawn mower from Screw??? - brill! Wouldn't use Eckman again - I think that the quality control is very poor; it is in very dire need of much improvement. I also used to work in Quality Assurance. You need to address this immediately - looking at the reviews I've seen on your site - mostly 1 out of five. Does that tell you something??
