Pressure Guard valve caps

[page3]

Anyone ever used these:

They look quite a good idea, as I find tyre pressure really has an effect on the S's handling. I assume you just leave them on - although it doesn't specifically say either way.

Just wondering...

I think many of us would consider a regular check on tyre pressure to be mandatory whether you had these or not, so a bit redundant really. Nice idea, but for me not necessary as I can't imagine relying on these any more than I would rely on the pressure to be "retained".

Just my tuppence worth...
