Review (4/5): Not An Electric / Vibrating Device
I got this hoping it would be a good alternative to the Z-Vibe tool with a similar design. It didn't work well for use as a Vagus Nerve stimulation device unfortunately. It's a bit uncomfortable to use on the ear as the tip isn't as soft as I thought it would be.
It would, however, be great for teething purposes so it does what it says it does.
