I replaced my 30+ year bed shaker with this one. I really like the big numbers, the super strong vibration, the flashlight feature. Also like the second alarm. So I am very happy in that sense. However, the settings are so impractical. I do not understand how come for the price of the device $80, they could not come up with a much more simple way to change settings like alarm, temperature and time. One has to go thru change of hour to end up in change of alarm, every single time. To change from C to F, from 12 to 24 hours time, there are three minuscule holes in the back for which I had to get a paper clip to change. They can do better for the price point. It has the best feature which is super strong shaking, just because of it I say is good. Settings however are very very frustrating....
