"Great!"
I've made many macarons in the past using the good old baking paper, and they have always come out lovely. However, being a perfectionist I wanted each shell to be exactly the same size which is why I bought this mat. This mat works brilliantly. I haven't had the trouble of the meringues sticking to the mat at all, just make sure you're using an Italian meringue recipe and not french meringue. I baked them for 4 minutes longer than I usually would. Also, make sure you don't under fill the mould, as they won't bake quite as round if the batter doesn't meet all the edges.
