Review on Optimized Clear 14-Ounce Sip by Arrow Plastics by Patrick Ross

I thought maybe it's not the best quality because you get multiple cups for the price and I was right. What I didn't expect is that after a wash, the lids would no longer screw onto the top of the mug. I don't see any warping of the lid or cup, but they keep falling off because you can't secure the lid. Just not a quality product. You get what you pay for.
