This is my first ultrasonic cleaner and it didn't disappoint!I purchased this to clean my Hitachi HSC32 carbs off my bike and man, what a difference! You can see in the video that, the surface rust was actually lifting away! (Results may vary).The carb bowls were nasty with 40+ years of grime and after 30 minutes of a "bath", excellent!I only gave it 4 out of 5 stars because it seemed to be just a little small with the basket in, but I get it, it needs to sit off the bottom so maybe 5 stars is more in order.The entire carb rack DID fit into the unit when put in diagonally though.(I used simple green prohd and water due to it's non corrosive properties on the aluminum bodies.)
