i got one quite a while ago the only thing is those whels don't take a lot of moving around. i taped one of my big cutting mats on the one side. so it is always there. plos i have a bigger one that goes on the other half plus the top when it is all up. i use one side at a time. really nice that it only takes up minimum space. had my mri before dinner so ihope to know by tomorrow whether anything is broke or not. stuck in minot having a blizzard right now. at least 10 inches of snow since 11 am.
