Review Content Good alarm for the money. My daugher is deaf at night when she removes her cochlear implant processors, so an audio alarm doesnt work. The vibrating alarm only wakes her up, so her roomates arent bothered. Programs easily and works well. It wakes me up with no noise. It does what it is supposed to do. Works well for any deep sleeper! This was the perfect gift for my husband who is a very deep sleeper. He kept waking up for work late. But this little watch wakes him up from the vibration! Its great! Wake up easily Initial set up was a chore--make sure you remove the battery and start over if you encounter ANY set up problem. After that--very light weight and does not interrupt sleep until it GENTLY, but insistently vibrates one to consciousness. The wrist strap is a bit cumbersome, but does the job. Cant imagine putting it on a belt and the belt clip is upside down. Silent Vibrating Alarm Watch This is a good vibrating alarm. It feels too big and awkward to sleep with on my wrist, so I put it under my pillow (in the pillow case). Its plenty strong enough to wake me up but not jarring. Its good and Im glad I got it. Kind of hard to get started Enjoy not waking up to loud music when it is not time for me to wake up. My husband can wake up silently. excellent, exactly what I paid for I use this alarm when I wake up earlier than the rest of my family so they arent disturbed by a loud and obnoxious ringtone. It does the job, perhaps too well if you share a room with a light sleeper, but besides that, its plenty loud enough to wake you if youre a heavy sleeper. I slipped mine inside my pillowcase instead of wearing the wristband as its very bulky for small wrists. Simple to adjust the time and settings, its been a good alternative to using a smartphone alarm. Product Defective I was extremely excited to recieve the producat because I awake early and dont want to awaken my partner. The instructions were simple enough but did not do what it said it would do for settings. I have called Sharper Image and they are sending me a new one which I appreciate. I will review after I get one that works correctly. I think it has the potentail to be awesome.
