Customer Reviews Stanley 30 oz/.88 L The IceFlow Flip Straw Tumbler

Not worth the money. This thing leaks - I am usually not harsh with reviews but two times already the entire thing has leaked water all over. Very disappointing. Does it keep stuff cold? Yes, but just the same as any other stainless steel tumbler such as my Yetis or Hydroflasks etc. The difference is those do not leak.

Have OCD and when putting the lid back on, the straw/drinking part does not line up with the Stanley name. Is not centered. Very distracting so I never will use it!!!

I don't trust this cup. First time I used it, it leaked in my backpack, everything got wet and ruined. That doesn't happen with my hydroflask or yeti. I feel like my money went down the drain because I bought two of these.

Junk! This water bottle leaks. Has ruined multiple books in my sons backpack. I tried contacting them to file a warranty claim. But that was four weeks ago and still no reply.

Looks great, but It leaks every time I use it. I've tried numerous times. It must be the black rubber washer on lid.

Came completely dented, scratched, and missing the straw. Very disappointed, Stanley.

It came damaged and I am still waiting for its replacement. I have made a claim that was accepted but nothing since then.

Definitely not leak proof. Water poor from the spout area even when closed.

It was my fav for only a month because then an issue started with the straw which makes it hard to drink from. It literally makes it really annoying to drink pure air with just few traces of water in every single sip. Don't recommend :/ I'd like my money back, it's not been even two months since I bought it.

I bought two and the lids leak all of the time despite being properly screwed on and tight

Love this water bottle and all it's features but the straw lost suction after about 2 weeks. I reached out to customer service because of the "fantastic" warranty 4 months later and I'm still using a water bottle with a busted straw because warranty inventory is different than website inventory.

Not leakproof, I placed it on my couch as I grabbed my stuff for work, it tipped over and by the time I got it there was a huge spill. Also, it does not maintain the cold! I put ice in my water at 7am and by 2pm the ice was completely melted. I work at an office so it was in a cool place not outside in the heat. Very disappointing as I enjoy my water cold and this does not hold up as it advertises.

I was sent a defective bottle. The bottom is not even and when I set it on a flat surface it wobbles. Looking at the bottom, it is not level.

Would be great...if it didn't leak! I've purchased 2. The second was to give it the product the benefit of the doubt, thinking the leaking was somehow use error. Nope!! These may work for you if you're not hiking, do not need a leak-proof cup, or just want one in a pretty color to decorate your desk! Otherwise, choose something else!

Came in with the top messed up. There was a part on the handle that looks melted almost. Also a lot of coloration issue like faded spots.

Does not keep drinks cold, had heard such great things about Stanley but will not be buying in the future

Unfortunately this cup is unusable. It is beautiful and I have loved other Stanley products, but when the straw top is flipped open and you try to drink, what you get is 90% air. I'm waiting to hear back about a lid replacement but as it is I would not recommend this cup.

It came damaged in shipping and most disappointing was the color accuracy to the website photos is not even close. My bottle was dull in color

My water in this bottle doesn't stay cold! All the ice is melted in just a few hours.

I purchased this tumbler after reading the article in the New York Times which gave it a glowing review. I wanted a larger tumbler for travel that would keep water cold when traveling in hot climates. I have smaller reusable water bottles but need a larger one when traveling or going out on hot days. The Stanley 30 oz tumbler leaks, it even leaks when upright. I will not be taking it anywhere. It is totally useless to me.

Not great. Certainly not bulletproof. Broke within a week. Not impressed.

I LOVE Stanley Cups, I have purchased over 10 of the 40 oz straw cup with handle for myself and for gifts. It is THE BEST cup. I purchased these water bottles to use while travelling. I bought 2 and they both leak. If they are at any angle other than straight up, it's gonna leak. SO DISAPPOINTED.

Love my 40 oz Tumbler but this one leaks every single time I use it. Super disappointed!

Leaks!!! Bought for Disneyland to use as an alternative to my Stanley 40oz cup with a handle and straw so I didn't have something that would spill in my stroller. Nope, everything in my stroller bag got soaked. Sad!!!

LEAKS! Not worth the money or hype! Should have just ket cheap store brand cup.
