Great product.
I've had one of these for a couple of years and I think it is an excellent product. Simple design, affordable. One of my associates liked it and got one of his own. I'm ordering a couple more to use with other colors so that when I go from white to brown and back again I won't have reload. I use two spring clamps to hold the unit onto my table and they fit inside when not in use. I store it in a clear storage tote. (A little oversized, but better than wrestling with the cardboard box, which is then repurposed for scraps.) Definitely recommend.
