Poor design
There are three main components to this device: the foggy-clear plastic case, the cartridge with 3 interchangeable barrels, and the handle. The plastic case shields the cartridge and is placed using notches at the widest ends to snap on. However, the notches are triangle-shaped, so you have to be exact with lining it up, and it is resistant to bending, making it a hassle to put on or remove.<br /><br />Changing barrels is even worse. It's not impossible but the "wings" of the handle are so resistant to bending. The alignment of the notches has to be spot-on and there isn't a comfortable way to grip the "wings" as you try to pry them apart to remove the barrel. I had to dig in with the tips of my fingers and was honestly worried about breaking my nails or accidentally punching myself in the face as I wrestled the darned device.<br /><br />I need to admit that I have not tried using this item as I wanted to return it in a better condition. The sticky material does seem like it would work well. Additionally, the barrel does roll quite freely once it's on.<br /><br />I purchased this with the intent of using a barrel, washing and removing it, using another barrel, etc and rotating through barrels as used ones dried off. However, the inability to comfortably exchange barrels makes this prohibitively difficult to use.
