Set of 6 Cooking Rings with Press

I'm not sure if it's worth writing a review, because it looks as though M & S won't be stocking them again and, probably, no-one will read this. I have to say I'm a bit disappointed in M & S. I bought the rings in the sale and I had expected a bit more product information on the web page and in the packaging. There's nothing to say what the metal is, whether they can be used in the oven, should they be lined or greased - I have used rings before but never in this gold brassy colour. I spoke to someone on chat and she couldn't find the answers, so suggested I write to 'retailcustomer.service@marksandspencer.com'. That was on the 29th September and have not received a reply, so I'm taking it that you don't know either! What I don't want is a pool of molten metal at the bottom of my oven. Surely the buyer can find out from the manufacturer. I've given them two stars because they look pretty, but are so far un-used so can't comment on functionality.

I have some larger rings similar to these but sometimes they are a little too big(depending on what you are using them for) I find the press utensil very handy for tamping the food down too .Ideal if you want to serve up your meal with a bit of a 'posh' look
