Product reviews for 4.3 Gallon (16 Liter) Copper Distillation Thumper for 15 Gallon (57 Liter) KEG stills

This thumper is great. It has an access to clean it or add something for flavor. A temp gauge in the vapor,  and a drain port. You could add a port for a heating element if you think you might need it. I didn't. You wouldn't be disappointed.
