If you recall, we had discussions about why there were no rating sites and how it was easier to get info on a garden post hole digger than it was to find out about a Uro. Someone just turned me on the these sites.
Hey, it's a start.
(Go with the Ace digger, it has wooded handles that are smooth and do not give you splinters and the hinge is strong enough to twist without breaking. I can't tell you anything about your Uro. Sorry.)
