QuCrow 30oz Vacuum Insulated Tumbler- Double Wall Stainless Steel Tumbler with Lid- Coffee Travel Mug- Indigo Blue

I was wondering how well insulated it could possibly be after seeing all of the reviews, so I did small test while just got it. I fill it with water and ice cubes at 10:15 in the morning (first pic), then just left it whole day, but came back to check after 12 HOURS. Pretty cool! There was still multiple ice cube remaining (second pic). I thought it would be good enough for daily activity already. And this point has been proved in coming several days while took it with me all day out. I understand some had different experiences but mine is great after several days accompanied by the tumbler. See the ideas I had for the tumbler, trust me, you would not get disappointed if you got one. -No doubt about the well-insulated.-Sturdy, durable & high quality while it is with pretty color (I love the turquoise one, highly -recommended).-Perfect to have it in car cup holder.-And the price is reasonable. Overall, this mug is really well-made and I am very satisfied. This tumbler is amazing and hope the review sharing can help. If yes, click the YES bottom.

Edit: I’m lowering my rating after buying my second tumbler, this one the 20 oz. version. The lid doesn’t seal well causing condensation to form around the top and drip down the sides. The powder coat finish gets pretty slippery when it’s wet so I have to lower my original 5 star review down to 2 stars.I’m so impressed with this cup! As soon as I got it I filled it halfway with ice and put it outside on my patio. It was 88 degrees F with 78% humidity. I checked it after an hour and found no sweat on the outside and not a drop of water from melted ice on the inside. Put the lid back on and left it for two more hours. At that point the ice had fused together a bit but still no water on the inside and no sweating outside! Where have you been all my life?! I’m ordering another one for work right now.

Love the color of this but it doesn't keep ice as long as the other brand we have. The other brand we have will keep ice in it all day long. This one is only a few hours. It is better than a standard cup but I expected it to do better. This also has a fun whistle when you drink from it. This is due to small hole in the top that allows air in while you drink. This can be annoying at times.

I waited to review this until I got to use it on a regular basis. the vacuum insulation part works good and will keep the drink cold/hot. the problem I have is that in less than a week the color was coming off in several spots even though I'd say I'm using it lightly and not abusing it. By the second week the bottom section has separated and cracked making the cup crooked and damaged looking. I contacted seller to ask about defective paint and seal on bottom hoping maybe to get a replacement but have not heard a word so now I'm leaving this to warn others. Spend a few dollars more and get an Rtic or Coldee

For a travel mug that isn't supposed to spill or splash - this does not work. The lid slide mechanism doesn't lock, so if the tumble is knocked over, the liquid inside drips/leaks out. I specifically ordered this based on the "leakproof" lid."Travel Mug and Coffee Cup FlaskWith Slide lid - No worry about splash or spill, this tumbler would be your perfect trip companion whether you are going for road trips, sporting events, relaxing at home, slaving away at your office, it is suitable for drinking coffee, water or beer. It would be your best insulated coffee tumbler ever. " NOT TRUE

I love it so far! I really just wanted something that wouldn’t sweat. I tested it right away with ice water and doesn’t sweat!

Love it!! I had heard from family that this cup really worked, so gave it a try. I use it mostly for cold drinks, normally fill this cup with ice & water, really surprise that it can keep the cold drink for all day long. I put some ice cubes in the tumble with cold spring water in the morning and the remaining water inside the tumbler still keep it cold after I get off my work. This is going to be a great product for me.

Great cup! Keeps drinks ice cold for over 24 hours. I love how easy it is to hold.

These are better than the expensive brand, kept our drinks cool all day while on our Mexican cruise.

Product looked just as described until we gave it to my son to use and the lid would not go on all the way, and the part that covered the mouth opening kept closing when he tried...

This is a two pack and one had a crack in the outer layer on the bottom of the cup. It is still usable, but not ideal quality I was hoping for.

As described. Keeps beverage cold for hours. Fits in cup holder of my car. I didn’t realize how heavy a large cup would be. Might opt for a smaller one in the future.

Love it. My fave color too. It does keep your ice drink cold for more than 24 hrs

I bought this to put my protein shakes in so they would stay cool as I sip throughout the day. Works great!

Keeps my coffee warm for about 4 hours. I love it, and this teal color is great.

I had this tumbler for work, just showed my colleague how amazing it is, then she bought 5 for whole family!!! You would know how good it is.
