The price for this cup seemed too good to be true and now I know why. First of all, I didn't receive the sliding lid, and the one I did receive is terrible. It doesn't stay sealed at all!!! The slightest touch pops it right out. I carry my cup from the top and haved dropped it twice because of that- causing an icy 30oz mess. I gave it 2 stars because it fits in my cup holder in my car and it does keep my drink cold, but without a lid that stays put, I won't be getting much use out of it.

I never write reviews, and I am here to tell you that this product is awesome!! I've struggled with regular cycles since going off BC pills in 2013, and I finally went to a naturopath to help the issue. She told me to take 3/day, and I got my first period in three months after taking these regularly for 2 weeks! She also prescribed me Vitamin D and a multivitamin, so I am not sure what caused my cycle to start up. However, I know that I will keep on taking this! I try to take this on its own (with a meal) to avoid the nausea issue, and it seems to help.
