Rambler 20-Ounce Stackable Cup

I bought this as my driving cup for hot coffee but whilst the cup size is great the hole where the liquid comes out is way too big meaning every time you go to take a sip, you end up burning your lips as the liquid comes out out too fast and too much. I am surprised actually no one has noticed this. Its actually really dangerous.

I bought two YETI 20 oz Stackable Cups for my wife and me, expecting the quality YETI is known for. Unfortunately, the lid does not prevent liquids from spilling, which was a major disappointment. I also own a YETI backpack that has a designated pocket for a cup or bottle. I placed the stackable cup there, assuming it would be safe for everyday use. Instead, my coffee spilled all over the inside of the bag, making a mess and soaking the backpack. This is especially frustrating since this is the bag I use to carry my laptop and other equipment. The cup itself feels well-made, but the lid design makes it unsuitable for carrying liquids in a bag. For a premium-priced product, I expected better spill protection especially when used with other YETI gear.
