Review on Cutting Made Easy: OriGlam Thread Cutting Stainless Metric – Unbeatable Deal! by Jeremy Choi

When purchasing it, some reviewers mentioned that it was small and cumbersome to use. The size is comparable to my Starrett thread gauge. Found that all metric threads are on one side of the gauge and SAE on the other side. I checked a couple of pressure gauges, they seem to be accurate. It's a Chinese-made product, but nowadays it's not. I would advise lubricating with a light oil to prevent rusting but I would recommend it at this price point.
