I originally decided to buy these OXO measuring cups because the price was reasonable and it has more cups then normal. At first I thought the extra cups were nice even though they are not really necessary.I've had them less than a month and already the numbers are coming off. LESS THAN A MONTH! I've come to realize the extra cups are actually a liability because they are hard to tell apart without the numbers on them. I would not buy these again. I feel like I've wasted my money. I should have just spent more money on cups with etched numbers on them.
