tesslux Electric Coffee Grinder

Coffee beans constantly get stuck in the grinder. Grinds a few beans, then needs to be disassembled to get out the stuck bean(s). Ground coffee goes everywhere and it takes a very long time to grind a supply with the starting and stopping.. After two days I am too frustrated to want to continue. No user manual included. Cannot find one online. This is going back. (I have used several types of beans. Same thing happens). I do not recommend.
