Query: Proprietary size/Only lets you use their brand of wax

I bought this warmer and thought I was getting a great deal. I also bought a 14 oz tin of wax, Gigi brand. Got the thing home, and the wax won't fit into the well. This company only lets you use their brand of wax! Gigi and other standard brands will not fit into the well. Since I don't "do" proprietary of any kind, I returned it. It's not the best quality, so I wasn't too heartbroken. Will buy another unit that lets ANY 14 oz tub of wax sit it its well.
