bought an Am tech 28mm pipe slice the other day,, most of other plumbing tools i use are top quality,, but as i'am only a diy plumber probably wont use it that often, thought id buy it because its cheap,, but the quality of this product is really shocking,, so i open'd it up, move'd the parts round a bit,, filed it down a bit, put a new wheel in it and its not that bad now... so what im asking is are all Am tech tools this bad or just picked a bad one up... thanks men
