I just bought one about 4weeks ago to replace a similar one that I had for quite a few years, I have only one fault I always with this one kept pulling the outside sensor in at nights when retiring to bed.
I never did with my old one the wire stayed out of the window all the time and never harmed it at all.
This one I forgot to bring in one night and when looking at the outside temperature it was reading zero, I then found out that the wire for the outside sensor had snapped clean in two.
I won't grumble though as it was cheap as chips less than 3 quid I use it now in another room as an indoor sensor, so be very careful were you put the outside temperature sensor.
I am now looking into a wire free set up.
