Onyx Vibration Alarm

I would say, after days of testing it, it works but only to certain extend. Sometimes, I wanted it to wake me up after a quick nap, it just can’t because I am a deep sleeper, and some weak vibrations can’t possibly wake me up (not even the annoying audible alarms could). So, overall, the product looks nice, serve its purposes, but I am not very satisfied.

I like the product but purchased MANY so I could give as gifts to all the guys in our family and extended family and the way it was shipped was in a flimsy plastic bag! And most of the boxes are damaged and definitely not looking acceptable for gifting sadly. I may return.

This is a good product. It appears they have made some good upgrades. The charging mechanism (from the instruction video) appears to be improved and the band clasp as well. They must have been clearing out old versions when I ordered. If you are purchasing verify you are getting the newest version as it can fall off in your sleep with the old clasp and the new charging method eliminates yet another odd cord. Still a much better way to wake up than an audible alarm.
