Ok, so our cool box is useless, no amount of pre cooling seems to stop it being warm 6 hrs later.
So I need to know, is an Icey Tek worth it? Will the 25l be big enough (we are a family of 4 and buy fresh as we go, iyswim)?
I know there have been threads galore on the Icey Teks but I need to convince myself it's worth the price tag...
