First let me say that this item is exactly what I need: a timer that vibrates to remind me to take medicine each hour. And since it is quiet I can wear it around my neck in movie theaters, lectures, etc. without disturbing anyone. However, it could be a little better quality. I wear it on a necklace. Soon after I got it the battery compartment came open while I was driving and spilled out a battery as I got out of the car. Luckily I retrieved the battery. This could easily happen if used as a key chain. The battery compartment is not very tightly closed. On the topic of batteries, even though this item is inexpensive, the first set of batteries lasted me only one month, and Radio Shack charges close to $11 for the pair. I hope my second set (bought this week) lasts longer. And setting the item is more confusing than most electronics. If I accidently bump a button while I'm out, the timer, alarm, and clock all go haywire, and I have to come home to read instructions to fix it. The buttons are not intuitive in any way. I'll use this timer for now. But if something better came along, I would probably switch.
