I purchased two of the Treekeeper XL Greenskeeper Rolling Christmas Tree Storage Bags for our 12' Christmas Tree. Going into the purchase I was skeptical that the tree would fit into just one XL Greenskeeper Bag. The tree arrived in two boxes about the same size as the Treekeeper bags so that told me there was no way all six sections of the 12' tree were going into one bag....but neither would I want it to. If you could get all sections into the bag you wouldn't be able to move it. Three tree sections fit nicely into each one. I emailed customer service before ordering to confirm if the wheels were plastic or rubber. I was told they were rubber. They are not. They are hard plastic that I wouldn't want rolling across my hardwood floors. I was able to find a set of 4" wheels (the wheels that come on it are 4.5") at Harbor Freight and have swapped them out. They roll much nicer, will support the heavy weight of the tree sections better and the bag will roll nicer across hardwood floors on the way to the tree set up spot. The bags come with two big handles/straps that are on top of the bag (the handles used to lift and wheel the bag are fine). To me the handles / straps are useless and I cut them off. There is no way to effectively lift the bag with these handles. I would have rather TreeKeeper put the money into better quality wheels versus adding the handles. I might try the internal straps but doubt I will hassle with using those given the three sections fit nicely with out them...again an area to take some cost out and/or transfer it to other components of the bag, i.e. quality wheels. A helpful hint when placing your sections in the bag keep the metal post end facing the opposite end from the wheels. If not when you pick it up to roll it those metal post section ends will slide down and into the canvas end of the bag...potentially puncturing the canvas like material. All in all a good solution as compared to other offerings available. The assembly was very easy once you see how one of the support rods goes together. The support rods (the internal frame) are put together in the corners with what appears to be a rivet. Once corner the rivet had come apart. I found it in the bottom of the bag, went to the hardware store and bought a similar size bolt, lock washer and nut to resolve. Easier then sending the unit back. The bags take up a lot of room so having a dedicated storage area would be a good idea. I would say if you are looking at storing a tree greater then three sections (you might sneak in a fourth section with some effort) you will need two of these.
