I got the Tower pan's and frying pans from Ideal World, the coating is very good but the pan lids are rubbish, after washing the lids the twice, I noticed water became trapped under the glass, I unscrewed the silicone top but I was unable to dry them because of a seal, so now they are rusting. I'm trying very hard not to wash them, only give them a wipe. Not very good, as Tower have been around for a number or years, that was the reason I bought them. Hope this will bring your attention to the fault. I would send them back under warranty, but the postage will cost . Mrs J D Turpin.
