I've had a chance to put this up to other tungsten grinders out there. I think its very similar to the Sharpie series for function. How ever the dust collector doesn't really work. If you have to trim off the tip of your tungsten it will not collect the dust. The collection tube is a bit bulky. With all that said it does serve the purpose of sharpening tungsten well.
But for the price this would not be my first choice.
