"I received the BAR338PA Atomic Clock and Time Projector as a gift. This device is quite ingenious and has quite a lot of technology in one package. It has a radio transmitter, two radio receivers, two temperature sensors, and a pressure sensor for weather prediction. Its two best features are auto sync with daylight savings time, and night time projection of the time on the ceiling in a way that does not interfere with sleep. The weather predictor is kind of cool, but personally I don't use it much.

Unit works well and one set of AA batts in the remote unit have lasted 1 year outdoors so far. Also uses only AA batts and plugs into the wall for the projection bulb. Well thought out procduct. Remote temperature part of the unit transmits in 400 MHz band, so no interference with cordless phones or Wi-Fi. Also, the website is very helpful and allows you to download the user manual online.
