not as spill proof as a brümate, but it definitely is spill resistant. overall it's perfect for what I need it for, easy to clean and I'm just happy with it.

Straw leaks
It’s great other than the straw actually does leak when tipped over. Got it on sale. Too expensive otherwise.

Great cup! Love Corporate Natalie
Not 100% spill proof when you turn it over but it is light and keeps drinks cold. Perfect for all you office warriors

Terrible Name!!!
I like everything about this mug, but couldn’t buy it because of the name. I don’t want the word “Reduce” on my cup. It’s like a constant reminder to diet. It’s a shame because there are so many cute colors, I like the size and the straw. But I can’t get past that “Reduce” printed on the side.

straw caused 2 star deduction
The spill proof straw is a wretched experience. you have to sort of bite pinch it in your mouth to drink from it, then the flaps impede the flow. It's like drinking through a coffee stir straw, or one from a kids juice box, only more annoying. I took a sharp pair of scissors to the flaps to cut as much out as I could. The rest of it is nice.

Love the size, not the straw.
I’m not a fan of the soft straw.

I now own 6 of these!
Love these no spill mugs!!! Will probably have to buy more if new colors come out. I already loved the 40 oz mugs but they have been relegated to the back of the cabinet as these are now my daily go to mugs.

The stickers on the lid are going to drive me crazy!
I haven't used my cup yet because I can't get the lid cleaned up enough to use. I assume the 2 stickers on the lid are to come off. I'm on my second lid trying to remove and keep destroying the lid

My new favorite!
I have other reduce products that I love, but these new bottles will be the only ones I buy from now on. I appreciate the fact that I can lean over in the middle of the night to take a sip of water without having to worry about spilling it all over me. I also don;t have to worry about the dogs knocking over a bottle and spilling anything on the floor. Love, love, love!!!

The product is ok
I use the product it keeps my liquids cool for long periods of time but the straw does not reach the bottom it's very frustrating

Does not leak
The only con is the stickers on the lid. They are very hard to get off. I still have them on. Otherwise, I love the cup! It really does not leak and the purple is pretty.

High quality cup!
[This review was collected as part of a promotion.] I have been using this cup for a while now, and I absolutely love it. It keeps my water cold all day long even without ice, it's hard to knock over, and even when it is knocked over, it doesn't spill. I've held it completely upside down, and not a drop of water escaped. I love that the top is clear so I can see how much is left, and am so happy that this fits into the cup holder in my car. It claims to be dishwasher safe, but I don't have a dishwasher, so I cannot say anything about that. But the wide mouth means I can easily fit my hand inside, so cleaning is super easy. Everything about this cup gets an A+ from me!

Great Tumbler
[This review was collected as part of a promotion.] This tumbler has done everything it has claimed. It was washed in the dishwasher with no issues. The spill proof straw straw actually works., It fits in the car holder. No wear and tear after a few weeks of use. Water stayed cold for several (8-9) hours. Nobody in our household doesn't drink their water for 40 hours so that wasn't completely tested. My son told me I really like this tumbler!
