I bought this machine expecting to work at an angle. When it came out I played around with it a bit to learn how to use it and things like that and then I removed it. When I needed it a few months later, it didn't work. DOA. gone but not forgotten. Kicked the oxygen habit. Take a nap in the mud. We examine the turnip with the help of a ladder. Late. I kept the carcass because the spirit levels work well. I see the same item for sale on sites other than Revain for twice the price of Revain.
