Review on Rubbermaid L33117R3SPA Litterless Juice 2 Pack by Derek Bates

I've been using this mug for about 20 years. I've never had any problems - they are great. I only replaced them because my son chewed on a straw or we lost them. These 2 bottles do not work. The straw's mouthpiece came out of one, and although it snapped back open, there wasn't enough suction to release the liquid. The other cup isn't absorbed either, and nothing happened. Very frustrating! I wonder if these are counterfeits or ones that didn't pass Rubbermaid's quality control! I will order from another seller, let's see what happens!
