The clock works. The display is reasonably bright, thus two stars. However:1. The instructions are terrible.2. The temperature reading is 18 degrees F (10C) too high.3. There was a little plastic flashing from the molding process that kept the battery door from opening. I had to drill and little hole and insert a screw to get enough force to pop it open.4. Good luck telling what the actual size is from the page info. It's much smaller than it appears unless unless the table lamp in the picture is really small. It's certainly not half the size of a pillow like one picture or half the size of a couch like another.5. It's just generally really cheap and nasty feeling.However, it does tell time and the display is reasonably brightly so 2 stars instead of 1.Changing the functions is complicate and I gave up mid trying.Really nice looking digital clock. Not too bright. Simple and uses USB cable.This clock works well it took me a while to set it up but finally got it to workIt did not come with a plug so it could be plugged into a wall outlet!~ It would have been nice to know that before I ordered it. It is still sitting in the box in which it arrived; I have to go out and buy a plug so I may plug it into a wall outlet!I am VERY DISAPPOINTED!!!!!I never could figure out how to program it! Seriously!Nice displayLike the way its displays
