very happy with my purchase.
it wasn't hard programming it.
follow instructions and you'll be ok
it does have a usb wire, but you can also put in batteries.
I did, in case you lose electricity, the batteries will kick in.
you won't have to reprogram again.
thankyou.
satisfied with my purchase.

very good product. recommend product and seller

Nice Clock! The screen is very colorful. The temperature and humidity readings are very accurate. The only thing that could be a little better is the fact that the screen is difficult to read when the lit background is turned off. What offsets that though is that you can set the clock up so when you touch it anywhere the backlight turns on. You can even touch the base and the light will go on. The price is right and the clock is very well made. It will be very useful for anyone who is looking for a small desk clock. I just noticed that the screen light can be turned on by clapping your hands. That is a huge plus and makes viewing the screen very easy. I really like that feature. Very Highly Recommended!
