A reasonably accurate piece of kit with limited information. I am not sure whether the tendency refers to the 6 hour forecast or whether there should be a barometric tendency on the display? There isn't on my box of tricks. Also the power connector is a bit dodgy and needs jiggling about to get the power on, otherwise it thinks the set is on battery and the screen switches off... Appreciate this weather station isn't for serious weather obs, and my wife likes the colours, and is happy with it. Thank you. Yours A Grumpy Old Matelot. Merry Crimbo.
