I've watched a few youtubers recommending them and they do look the biz tbf as you can pull really tight bends very easily. A couple of other plumbers I know luv'em, no formers to carry around only problem is you need one for each size but they are so much less of a faff to use the benefits seem to outweigh the overall cost and inconvenience of carrying around two sets but they are smaller and lighter than combi benders. I'll get some sooner than later I expect.
