Beadrollers
I think they are all pretty-much the same. They are built CHEAP so I just expect to make some "improvements" when i do buy any equipment that's "Cheap"!
The WHEEL instead of the crank is a definite improvement, especially if you work by yourself.
The Tensioner needed repair/replacement on mine also. It wasn't a big job but it does take a little time.
The old truck rim I used for the base was ok, but I added some Quick Concrete in the upper part to give the unit some more weight and it keeps small things from falling through too. Some light cardboard covered the holes in the rim before pouring the concrete, and just "goes away" after while.
(I'm waiting for those cheap electric winches to GO ON SALE so I can add that to my roller instead of the Wheel.)
