Rating : - Not as good as previous model
I bought this because a previous model I had worked so well. It used to have a boxy shape and the lid covered all the buttons. I had it for a number of years before it gave out. This new style lasted about a year and then it wouldn't keep time despite changing all the batteries. The vibration wasn't as strong as my previous model and I found that sometimes it didn't go off at all if the pressure from laying on it hit it in the wrong place (where the turn off button is). This is because the cover doesn't protect the buttons sufficiently. I know I didn't just sleep through it because a few times I woke up before the alarm and realized that even though it was set it did not go off so lucky I woke up. I found that in order to make this thing work for me, I had to clip it to my pajama top near my neck (not comfortable) or if I had on a long sleeve top (not a loose sleeve), I could put it in my sleeve so that it would wake me up and not get turned off in error by pressure under the pillow.
