Hi Gord, This is actually my second Elio drive. I have had one for six months or so and love it. It is amazing how such a simple device works so well. I have yet to have a bowl become uncentered with the Elio drive. I bought a second because I will be teaching a new wood turning class at the North House Folk School in Grand Marais, Minnesota. So, I will introduce the Elio drive to students. Hopefully you will get more orders from this neck of the woods.
