The product is great but could use some upgrades to make it better. I suggest to throw the supplied polishing beads in the trash. Not knowing I used them and apparently they are steel. So while in the canister after my polish process. The beads turned to rust and stained the canister. Not Good. Also the lid is hard to remove because it has no handle of any kind to tug on and you literally have to use a knife or flat blade screw driver to pop it up.
