They're really, really good pad. I've had mine 4 years now, and it is honestly as good as the day I bought it, the foam is very high quality. I did hear that they stopped using the expensive high density foam shortly after I bought mine, in favour of the cheap crap that wears out quickly. Maybe they've started using it again I dunno, will have to check when they appear in the shops. Only downside with mine is the plastic underside, great for floating on cow shit at Almscliff but a lethal sledge of doom under deliverance if it's wet. Don't think they have this anymore either.
