Looks the same as isonic, under different name.

Only one 80W transducer to 49 KHz - is this a big disadvantage against basic 3 transducers cleaners, or for this application normal?

Also, when they say 80W, is it meant per litter or is it total? Kind of misleading.

I could not find any specs for HumminGuru, how many transducers it has and at what power they are applied.

Anyone has used these machines?
