I agree.
I think it's a big waste. When T talked to me about getting a new one I said (after a lengthy discussion) "it's lasted 4 years past it's expiry date anyway. What's a couple more months going to do?" (guess who won that discussion

)
Personally I think the "expiry" date on those are ridiculus. It's plastic. Plastic doesn't degrade as bad as it needing an expiry date..
I'm thinking it's another example of overboard Health and Safety.
where's all the excitement in life gone? dead and buried under a crapload of paperwork....
