This product is basically worthless. It is so underpowered that when the blade slides to the side of the stone (and it does slide to the side of the stone), it comes to a complete halt.
One star is much higher than this product deserves. It is a complete waste of money. This article says that it is manufactured in the US. If so, they ship it to China to come back. The one I received was shipped from China, and it says on the plate holding the batteries in place "Made in China." Hang in there.
Bottom Line: No, I would not recommend this to a friend
