I have Line Plus on my bike for maybe 2 years or so, half of that time during the day parked outside, and had no water problems whatsoever while we do get plenty of water from above.

I have to admit that I avoid that website due to strongly biased opinions there (and tilted towards Philips) - I do not even want to get subconsciously influenced . The site's author posted also here.
