I had a lexan cafetiere once, bought from Cotswolds. All was well for a while, and it was very good for brewing coffee, until the plunger bit broke.
Last Christmas, my girlfriend got me another. But after just one week's use on holiday, that too broke the next time I used it.
Either I'm very unlucky or the ones Cotswold used to sell are crap! I haven't seen them on sale recently, so they probably don't stock them any more. It's a shame, because they're a good idea if they could be well made.
I just use the jug method for making coffee now and filter the grounds out through a tea strainer.
