Finally I'm going to ask, after long times of wondering.
Every once in a while this topic comes up and everybody advices at least to cover the controls from the rain. My question is; WHY?
I'm asking this question because I'm wondering what makes the difference between the US
ECV's and those in our neck of the woods. While England might be more famous for it's reputation of always having rain, the Netherlands is doing it's best on that department also.

Winter, spring, summer or autumn? Morning, afternoon, evening; rain, rain, rain, rain. I've experienced Florida getting a lot of fluids in a very short time, but then again that's no different than I've experienced at home frequently enough. Because of our social system, there is a huge amount of ECV-users. Combine all of those ECV's an all of that rain, and it results to ECV's being out in the rain all of the time. And yet; nobody ever covers their control out of any 'need'. Heck, user manuals will even inform folks it's not needed, the ECV's can take quite a 'drowning'.
Done the same thing myself for years, never ever a problem. Well, perhaps apart from a wet bum if leaving the seat unprotected out in the rain.

In our council alone there are about 200 ECV users. Never had one report about a control malfunctioning because of being exposed to the rain. (have to say that maintanence also falls under coverage, and I'm part of an adviceboard in our council and keep an eye out for any of these types of problems or other common malfunctions).
What makes the American ECV's so different to the Dutch ones that the first apparently need covering of the controls while in the rain and the latter doesn't? Or are it rather the users that make this difference?
