This is the second VEVOR 1x30 sander I bought. These are an amazing unit for the money. I have 2 side by side that I primarily use for sharpening knives.

After years of researching and thinking I had to purchase a full blown belt grinder in order to fulfill my ambitions as a amateur knife maker I finally decided for this small VEVOR 1x30. It arrived in a very well sealed and protecting package and installation was as simple, as shown in a myriad of YouTube videos I had been studying online. It seems that earlier items had some quirks involving the tensioning wheel, tracking when switching direction which apparently forced people to follow a course in computer programming!? It must have been my unusual gift for fortune but none of these mishaps happened: the tensioning wheel was chamfered, tracking is flawless in both directions, every nut and bolt appeared tight and reversing is a simple matter of stopping the machine, pushing the orange S button on the control unit for 2 seconds until a red dot appears in the lower right corner of the screen and presto! I must confess the latter procedure I stumbled upon in one of the videos on YouTube and is not mentioned in the documentation at all, as is any information concerning the four buttons. Hopefully in an upgraded manual there will be some more info about the control unit (which originally seems to be designed for a sowing machine , so what!). And last but not least the motor is remarkably strong and silent, making it easy to grind away even thick metal sheet. In short: a bargain for anyone looking for a very affordable, compact, very strong and easy to use belt grinder!
