Drinks don't stay cold long

I 90% love this product. It accomplishes what it set out to do. But it fails on two very important parts. 1. The agitator. On its own functions great. But it’s placement causes a problem. It blocks some of the liquid from leaving the bottle. So, there’s always some remnant that you don’t get. You could remove the agitator, but this has proven to be messy and an added hassle to deal with at the gym. Which brings me to: 2. Even this the agitator removed, the cap is pressed form plastic. Which means there are cavities in the lid that prevent all of the liquid from going out the top. It feels to me like they didn’t do a thorough product testing. Both of these issues have easy resolutions, just not sure they will get to see the light of day. Until then, I will live with knowing this bottle will continue to deprive me of feeling 100% satisfied with finishing my drink every time I use it.

Este producto cumple muy bien su función, lo mejor de todo es que no se filtra nada y y tiene un buen agarre

I drink a lot of water every day, along with a couple shakes that I make in whatever water shaker cup I'm currently using. I'm pretty particular about my cups since they are always on me. I went with this 36oz because I'm always looking for the largest shaker cup that is still small enough to pick up and carry around easily (I like them to fit in a car cupholder). I was excited though a little hesitant to spend $45 on a shaker cup. The shaker wins is great in most areas, however a couple of negatives below: 1) on mine, the top is tricky to get to thread on. I asked here and others said they did not have this same issue. 2) The bottle is somewhat slick, especially if you don't have large hands. I put gun tape on mine to give it better grip. 3) The LID actually forms condensation. I've used many different brand shaker cups over the last 10 years, including an earlier version of this Iceshaker - never have I ever experienced a lid building up this much condensation. There is enough that when you first tip it over to drink, you will get water dripped on you. So it seems the cup is very well insulated, but not the lid. Too bad. 4) NOT RETURNABLE - when I checked, this item is shown as not returnable. $45 is a whole lot to pay for a shaker cup, and then for it to be "not returnable" was just insulting. I understand some products (personal hygiene needs, etc) can't be returned due to health codes ... I cannot for the life of me imagine any valid reason that this is not returnable.
