This is good in theory but actually a waste of money- priced way to high given the poor design and quality.  It’s really large but quite flimsy - the rollers don’t really work for a quality heavy tree since it’s very hard to lift.  Needs hard sides - literally just a bag on wheels - and lack of sturdy sides makes putting tree in really difficult.  Also - our 10 foot tree barely fit in this even though it says it will fit 12 foot.  You’d really have to cram a 12 foot full tree in this bag!  Overall quite disappointed!  Kind of hate it actually.  I would have returned but needed something to store my new tree in.
