Query: The lid is way too tight

my main problem with this cup is the lid is absurdly difficult to get on. I was amazed at how much trouble I had considering this is a name brand cup. I suspected the problem could be me, so I handed it off to a male to see if he would have equal trouble as well - and he did.The cap on top of the lid takes so long to coax into place that the only way I've deemed this cup usable is to just leave it closed all the time. Other than that the cup seems to be fine. The markings (c, oz, and ml) are clear and readable. It is also easy to clean (if using protein powder it is probably best to rinse it out right away), though I cannot say how it fares in a dishwasher. If you do not want a cup that is a hassle to put together and you are just making simple shakes, you will probably want to look elsewhere.
