Dont use the RS0001!
Its not very good (I am being polite) and you will be wasting your money.
thx for the warning and yes, have read them....
But as I have the outside temp&humidity on the north facing wall I'm not requiring much solar protection need from the RS0001 - it's more to protect from all the other stuff, like rain.
(My Lacrosse with an much worse protection worked very well in same place for years...) The WS 57 lightning detector is also inside a RS0001 inside it's plastic bag and I'm not too concern if late evning sun reaches it.
It also comes down to what you need - and as in my case I don't need protection from sun I don't see having the RS0001 as a major problem...
But I do agree - now seen the RS0001 unit... I would not recommend it for protection shield in a sunny place.
