works great! they are pretty heavy and can be tiring to fill at the grocery store trying to hold the nozzle up for lengths of time while filling multiple. They do tend to want to roll around a bit. They are well build though and I think they will hold up for a long time. It takes a few days to get completely dry before folding and storing away. Being they are heavy the handle can start to hurt your hand if holding for more than a minute or two. I love them for being so storable.
