I brought these on the advice of a friend. I have to say that they have been excellent, not one wasted. Usually you get a few that you have to use as coasters or just throw away, not in this case. I recommended these if anyone out there is a first time buyer. Yeah I know the the price, but like I said not one wasted and that to me is very important. So is it good value? The answer is yes they have worked like a dream, excellent buy.
