Stopped working at 2-3min the very first time.
Purchased at a CVS over holiday season 2021. Had thought about buying more for gifting if worked well for me. Installed new batteries and followed directions 100%.  Turned on and it vibrated for about 2-3mins before stopping.  Turned on and off again.  Light comes on, but no vibrations.  Not a huge loss for what I paid, but have to share for others that I wouldn't recommend this. You can soak your jewelry in solution in a glass bowl for free. Glad I tried it out before purchasing a lot to give as gifts!!
