Just read the website.

"Rigorously tested to -18C"

Which says it all. No use in Scotland in winter ... nor in very cold parts of the UK..

Andy,

Not at all, Just driving my truck down a snow covered single carriageway with a filthy salt covered screen due to frozen lines/screenwash (used neat) combined with a low sun recently and decided to look in to solutions.

I've ordered one anyway for the truck, if I can't fit it to that, I will stick it in my car. I did buy heated washer nozzles off ebay for a Vectra C for £20 as well.

Someone else suggested putting meths in the screen wash bottle along with neat screen wash.

Judging by the number of people stopped on the hard shoulder of the motorway cleaning their screens manually, it's a common problem in cold weather.

Each to their own though....

I think a large part of the problem is down to people having to leave their cars outside all the time so the entire car eventually cools to the same temperature as the air, thus the washer bottle freezes and the windscreen takes longer to reach a temperature where the fluid doesn't freeze the moment it makes contact.

The ideal system probably needs all three - heated fluid, nozzle jets and windscreen. It only needs one of these to freeze for the whole system to stop working.
