Enrossi wheel rake (good or bad?)

I am going to look at a 10 wheel Enrossi hay rake this morning. I have heard of these before, but never seen one. Does anyone on hear use one or know any good or bad points about them? Any help would be appreciated. Thanks and have a good day.

It is a fold in them midle type with 5 wheels on each side. I went ahead and bought it. It was in pretty good shape. Someone had added some extra support brackets to the arms. It had new tires, new hydraulic hoses and decent paint. It is missing about six teeth all the way around. I go the rake and four extra wheels off of salvaged rake (bearings,teeth, and all) for $1500.00 delivered. I used it yesterday afternoon and I see what you mean about not doing so good in heavy hay. It balled up a couple of times in some wheat I was raking. I went about 400 yards and the whold right side of the rake fell off the frame due to the Ubolts being loose that holds the bracket on. Once that was fixed she did fine. Thanks for the input guys.
