I believe I have the same brand, got it for Christmas two years ago. It had two issues, no matter what time you set the station at, it reverts to perfect PST within a few minutes, I gave up on that one. Never could get the rain gauge to transmit to the base station. About a week ago the base station batteries went dead, I replaced them and the barometric pressure is now exactly 1 point low. If my barometer says 30.23 the weather station says 29.23. Maybe Chinese barometric pressure is measured differently?
