Took ages to come - I must read the source location carefully - but that's my fault.
Well made works perfectly and seems accurate hen I stick it out of the car window.
Tips: For the mechanically disabled take the supplied yellow cover off to install the battery. Also it needs to be held square into the wind to give an accurate reading so I have attached a length of cassette tape to to top to act as streamer so I can align it properly.
