Stanley 30 oz Stainless Steel Ice Flow Flip Straw Tumbler

Jump to the conclusion, It is hard to clean, impossible if you don't buy specific cleaning accessories. Used this for half a year, molds EVERYWHERE The details: Since I bought it, I clean it thoroughly every month and almost always only hold water with it, sometimes water + soda. Around the third week I received it, I found mold by the corners of the flip lid and on the rubber on the lid. I used an electric tooth brush, those that viberates, to clean it, still can't get to the bottom of it but because it is impossible to pull the rubber out and stuff it back, I stopped when it's visibly clean. Same thing happens every months until yesterday I found molds inside the water bottle by the screw marks where you spin your lid in. I was concerned, therefore i dissembled the whole thing, only to find out after the toothbrush cleaning, boiling water washing and hand washing, there're still molds inside the transparent straw itself, passed down by the flip straw on the lid. After looking into it with flash light, i found molds ALL OVER, covering the entire inside wall of the flip straw. It is absolutely disgusting, and i don't know how long i have been drinking those molds. It is so not noticeable because you can barely see the inside of the flip straw even with flash lights, and who will think of cleaning somewhere you never thought molds could occur? I mean this is a water bottle, why do I even have to think how many parts i need to clean? Never ever had this problem with any other "simple" water bottles. The designers really should take this into account instead of advertising how cold this can keep water. To have a nice cold water, you first should trust your water bottle enough to drink it. Pure pure disappointment. See attached photos, the boxed part should be entirely blue if no mold Only good part is it's big enough and it didn't break down after I drop it a few times...

Works good and looks nice my girlfriend really likes it

Great cup! Keeps ices for days! The color is super cute.

so pretty. The engraving was flawless. really love it. The color and texture are top notch.

The kid loves his bottle .. it’s for school .. love the color .. stays cold.. goes thru a different bottle every school year.

#1. What I didn't like was it was packaged pooling. My son's Stanly cup has dents in it and scratches. #2. I paid lots of money for Target to ship the stanleys poorly. #3 I should get a full refund and replacement for it.

Opening and closing the spout is next to impossible unless you’re hulk. It’s also very wobbly. Very disappointed unfortunately.

Best water bottle item I’ve owned. I like that I can fold the handle down and the bottom fits in my car drink holder. I like that I don’t have to unscrew anything.

Easy to carry, leak proof and keeps any hot or cold for hours

Perfect for travel. Bought it specifically for me next road trip

The cup is really nice, it does not hold cold temperature as long as I would like and it isn’t leak proof which is why I changed styles.

The tumbler looks exactly like photo. Keeps my water cold and takes quite some time for ice to melt. The tumbler fits in car cup holder. The handle is nice and spacious so easy to carry.

Absolutely Love my Stanley! It fits on the sides of my back pack when I go to work, it’s the best thing ever

I bought this a month ago the best flask ever.I really recommend this Stanley cup,or any really best brand I ever bought from other then yeti.

Great for travel baseball. We got 3 for taking with us for all day at the ball park

Everyone says their cup is the best, in my opinion Stanley wins, bought one for me and my boyfriend and he loves it!

I absolutely love my IceFlow Tumbler. The handle is so easy to carry, and the 30 oz. is the perfect size. The color Hydrangea is beautiful.

Perfect! It’s exactly as I’d hoped and I use it all of the time!

Perfect for walks and sports. Easy to carry handle.

I have got 3 stanlys at the moment and I am thrilled with every single one definitely press add to cart quick!
