Query: Don't waste your money!

Bought this to replace a Taylor suction window thermometer. There is absolutely NO WAY this pseudo suction cup will stick to any surface as there is no center to the suction. This item was too inexpensive to return (the shipping would have killed me) so I just threw it away and bought a similar item at my hardware store. This one works perfectly, adheres to the window surface from the first installation, and was the same price AND, guess what? It's a Taylor!
