Yours was better. I Loved the Buzz of yours over mine but I haven't tried all three yet. I been working on it a jar at a time but I know yours was better then the 1 I had. I really want to see what you think of them when I can get a vac sealer. I bought the plastic. I need to just break down and buy one that and a food dehydrator for when I can grow some mushrooms. Yours had a better buzz but I still have two to try. Now that you reminded me I have to try the others, Oh boy like a kid at Christmas I have a couple new toys to play with Lol
