ROCAM Alarm Clock with Bed Shaker for Heavy Sleepers

it lasts forever, the vibrations are so strong and have 3 different levels. this works in old rental unit where sound can travel well. It does not work my neighbors.

Long battery life, loud vibration, allows vibration-only alarm (nearly vibration-only, a *very* small amount of alarm sound still plays but is drowned out mostly by the vibration sound), allows two separate alarms, has dedicated button for vibration intensity (on back), customizable day of week for alarm to play (choose between M-F, M-S, S-S per alarm using dedicated buttons on back), rechargeable so doesnt need to be plugged in (more alarm clocks need this functionality), has a wrist band so it doesn't fall out of your bed. Only criticism is the long pressing vs short pressing for setting alarm times/turning on and off alarms is flip flopped, but you get used to it after a while. Not a functionally significant problem.

Great little clock. Holds charge for a long time!!

Wife's patience wearing thin? After countless mornings of hitting snooze, I finally invested in a vibrating alarm clock. It's been a game-changer. The vibration is discreet, unlike the disruptive beeps and buzzes of traditional alarms. While I initially worried it wouldn't be strong enough for a deep sleeper like me, it's surprisingly powerful. Plus, it has a switchable sound mode for backup. A gentler wake-up (and maybe for your partner too!) There's a chance it could still wake your partner if they're a light sleeper, but in my experience, that's only happened occasionally. Even then, the vibration is far more tolerable than a blaring alarm. Bonus benefit: a calmer start to the day An unexpected perk is the more peaceful wake-up experience. The vibration is gentle compared to a jolting alarm, and I find myself easing out of bed much more readily.

Fairly easy to use. The back switches are easy to understand and to change the alarm times you press the buttons at the top. I'm not giving this a 5 because over time the volume and vibration weakens and it's not as strong. I've had this for less than 6 months. It's not durable either. One of the buttons dented in (still works) after it slid off the bed onto the floor. I guess that's user error but idk how to control the device's lanyard from slipping off my wrist while I'm sleeping. The lanyard doesn't have a tightening clasp so it's just loose. I don't think it's worth the price tag, if it's around $10 I'd say it's worth it, but I can't justify it right now.
