Negative Positive
Title: Disappointed
Review: I purchased 3 of these mugs after reading the customer reviews at this site. Unfortunately, the mug lids are ineffective. The opening where the liquid is supposed to flow through (so you can drink it) is so small it's impossible to get a sip. I tried returning them and had 1 successful return transaction but now have 2 mugs which are not usable. I've tried using a screwdriver to create a larger opening and I've tried stretching it with various utensils but the lids end up the way they started: not functional.In defense of the mug, the one that works is great. I just paid $36 for 1 instead of 3, and have had the hassle of trying to fix the others without success.
Is the review positive or negative?
