My Tefals ones (i brought two maybe 4 or 5 years ago have begun to lose their non stickability, still functional but...
They were about £20 each iirc and there are several diffent quality ones even within the Tefal range, i didnt go for their cheapest offerings, thsse have done ok.
It was a revelation to be able to cook stufff, eggs particually, without splitting them all over the pan.
Id buy them again. Tried some white ceramic ones some years ago, never got on with them but as i cant remember the brand or name...bit irrelevent really
