This company is a terrible company to deal with if you have any sort of issue and I mean that, if I could give this company - stars I would and they deserve it. I purchased a set of taps that had a fault as soon as they were fitted . I emailed the company and that's when it all went down hill, refusing to give a RMA number so can not return want a video so would have to pay to get these installed again and then send to them and I am sure more stalling. Blaming the manufacture and saying wait for them to come back to them. Complete lies as the contract is between me and the supplier not the manufacture QS Supplies know the law. I now have a set of taps that they will do nothing about. So if you have a issue good luck the only good that has come out is that no more business from me and none from a work employee which would have been a nice order to get, and make no mistake QS I will discredit at every possible chance as they deserve it. It is the must degusting vile company one could deal with, pay a bit more and get real service I was going to say third world but that would be a insult. Take my advice and stay well clear or you will regret it.
