SmartShaker‪+‬ 4+

The smartshaker 2 does work better than the previous smartshaker as it does vibrate hard enough to wake me up but it has problems reconnecting as it keeps acting like the phone is out of range even though it is next to it. It does work good once you finally get it to connect after several attempts.

It really does the job, no way you will not wake up, fairly strong vibrations to wake up even very sound sleepers.

Only wish application could connect to more than one Smartshaker+. It need not connect with more than one at a time, but rather be able to "see" additional devices one at a time.

Device is inexpensive enough to keep one at home and one at vacation home and one packed in suitcase ready for travel. Adding capability seems a simple software change.

when the alarm actually works, it’s fabulous. doesn’t wake up my roommates and still wakes me up effectively. but to change the alarm time is such a hassle as the app will never let me sink to the actual device. i’ve tried every possible way - opening the app and then turning the device on, having the device already on when i open the app, doing them at the same time, etc. and nothing works consistently. i’ve had to frequently delete the app and redownload it in order to get them to sync. very frustrated and disappointed in this bad connection.
