The connectors are
made of weak plastic and began breaking when I started putting the unit together. Then as I managed to assemble some of it, it wouldn't stay together. The wheels wouldn't even fit through the cover, and when I tried to put the cover over the unit the entire thing collapsed!
Per eBay's policy I cannot send this piece of junk back because of the damage it's sustained as I tried in vain to assemble it.
So, I'm stuck with a
heap of useless metal and plastic and I'm out of one hundred bucks.
The guy who invented this needs to be arrested for robbery.
It is very quiet, effective and easy to use. Folds up to save space and is light weight. It is on wheels making it easy to move. I recommend this product for anyone.
