Review: Works pretty good for degassing silicone and pu - I bought these to make vibration wands for degassing silicone and pu when mold making and casting. an Old "ultrasonic" toothbrush seemed to work ok, so i figured i'd try something a little stronger at a similar vibrational frequency as I don't have the money or room for a vacuum chamber right now.
Review: Worked as expected! - I had a student making toothbrush robots and these worked great. It was easy to use and made the robots move.
