No need to shout, MM. Nowadays, if I'd bought an expensive product & found it lacking, I'd return it to the shop/manufacturer before p'ing about with it...
Few years back, bought a faulty new gun from a v famous maker, tried tinkering with it. Luckily, with the support of the dealer, got it repaired. Should have sent it back straight away.
