I have been very happy with mine and very pleased with their customer service. I broke a plastic part through that I think was my own fault in not tightening a knob. They said no problem it should not have broke and I had a tracking number with a new unit in a couple of hours.
On the tips, after reading all the negative posts of others, I find that I undergrind the tips and then need to go back and retouch them. If you round over a tip, I think you are running the unit fast and not paying attention. As someone said in another thread, if your rounding a lot of tips, you might not want to sharpen knives. I have the BGA but like to use the base angle guides for setting a regrind angle. I recently did a set of 20 year old Henkles that looked liked they had been partially sharpened with the wheel on the back of the old electric can openers! The KOWS cleanded them up nicely and my sister is a happy camper.
Start coarse ans set the angle and quicly move through the belts. On cheap fillet knives, its like 2 passes, on hard powdered metal knives, it takes longer than you think. Go slow and you will be impressed with the results.
