It’s a great clock/timer. Everything on it works as advertised. The numbers are BIG, which I like, and the dimming feature makes it useable anywhere. The directions are well written and easy to follow. So why the four stars? The remote has a problem. It works great, no problem there. The buttons have excellent, crisp printing, which is important because there are lots of settings and things you can do with it. The problem is with the battery door. It’s the kind you press on, and the cover bends a little to allow you to slide it past the tab that holds it. The problem is - it doesn’t bend at all. I had to put on latex gloves to get enough grip to slide it out the first time. After you fill the battery compartment, the batteries themselves are in the way and the cover won’t bend at all, making it impossible to get it open that way. I had to slap the remote against my palm a few times to get the door to come flying off and the batteries to come tumbling out. Maybe yours will work better, but that is the experience I had with mine. Minus one star.
