I ordered one of these off Ali Express. An oscilloscope app showed it was about 40Hz vibration from the weight on the motor, far far from being ultrasonic. Got a refund, it ended up in the recycling.


I use Google Assistant a lot. I tried the Gemini Assistant on my phone and it was an exercise in frustration.
Me: (after pausing the tv) “Resume TV”
Google: (resumes playback on TV)
Gemini: “TV not recognised. Please say the device name” or even worse… “A resume is essential when you’re looking for a job in television. Your resume should blah blah…”
Me: (with phone locked) “set a timer for xxx”
Google: “setting a timer for xxx, starting now”
Gemini: “I’m unable to set timers, please unlock your phone, open xxx and (lengthy step by step instructions)”, or “setting a timer for yyy” (completely wrong time).
