Sursip40 oz Insulated Tumbler with Screw Lid - Stainless Steel Vacuum Cup with Straw and Handle, Keeps Drinks Cold up to 24 Hours - Sweat/Leak Proof, Dishwasher Safe, Fits Car Cup Holder (Waves)

So for a while now I have been looking for a big enough cup. That will allow me to drink water without having to constantly fill it up. Also I wanted a big cup to kind of keep track of how much water I'm drinking. I bought the 50 oz. And at first I was not happy with my purchase. Because the cup leaked, but After asking people on Amazon and reaching out to the company, I realized that I had received a defective cup. Without any issues, the company was able to send me a replacement. And I have to say that after testing it out, I am very happy. This cup is great quality for its price, it is leakproof, big enough, and it definitely keeps water cold. I can only attest to keeping water cold. Because I haven't tried with coffee. I did fill it up with cold water and left it in my car for over 6 to 8 hours in the hot weather and my water was still cold. This cup also comes with 2 different straw attachments. In case you want a bigger straw and a straw cleaner, which I think is awesome. I am very happy with my purchase. And this cup is well worth it! I am thinking of purchasing a couple more as gifts.

I'd like to give this 4.5 stars because it's so tall it won't fit under my ice dispenser. However it's a small issue so I gave 4 stars. I've always had a Yeti or Yeti style insulated cup that I keep handy 24/7. After the second time I knocked it off my nightstand and was sopping up water at 3 AM, I decided I needed something with a tighter lid.This cup has a screw top lid which keeps it from going flying. It included a metal straw and two sizes of silicone straw tips to one isn't knocking one's front teeth out on the metal straw. It does fit nicely into my car's cup holder and it's an attractive color.I'll probably order another for "back up".

I love everything about this tumbler, the color(purple/teal), handle, size, twist top, and the fact for being 40oz it fits in cup holders nicely in my and friends vehicle. I carry a beverage with me when we go out for short and long trips. Went out to go shopping and out to eat. The outside temperature was 100 plus and this tumbler set in the vehicle for 5 hours and my tea was still ice cold when we returned. About as good as it gets!

I bought this for my cousin and she loves it. She fills it up with ice and her drink and it stays cold all day and even into the next day. And my cousin and her husband was going somewhere he asked her what she was going to do with that it won't fit in the cup holders guess what it fits. Would definitely recommend this cup for anyone. 💜💜💜

I drink ice water like it's going out of style. This cup not only keeps my water cold all day long, my ice last all day, I usually feel it about 3/4 full of ice then fill up the rest of the way with water and replace the water as needed throughout the day. It does not sweat which is a big thing for me. It may dribble a tiny bit if tipped over but it does not leak. And it fits perfectly in my cup holder and my 2017 Ford fusion. I love the option of using the straw or being able to take the straw out and drink from it regularly. My only complaint it is on the heavier side but I can look past that with all the other wonderful features. I'm glad I took a chance on this and didn't drop more money on the Stanley cup that everybody seems to want and have.

It has been keeping water and some ice cold for 11 hours straight, which is great haven’t tried the 24 hours yet, I got it so in the morning I would have cold water to drink,The only thing I don’t like is the lid , it’s a screw on and the straw is in the middle, I find it hard to drink from the middle. You can remove the straw and drink from side , but getting a straw in with the frozen ice is hard and getting the drinking hole to the side you like to drink from is very hard. It would have been nice if it came with a push on lid as well so you had the option. 👍🏻

Love the color and versatility of opening. Somewhat durable. Got knocked over by a friend and now the handle is chipped. Some issues with fit of plastic straw fitting that makes loud noises if not on tight.

I love that it came with a metal straw and a rubber overlay to cover the straw for easier sipping. Keeps beverages cold. I only wish the handle were a little longer because it barely fits 4 fingers in it to pick it up, but still worth the money.

The media could not be loaded.  Me encanto súper lindo el color no se sale el agua solo cuidado que no perder una goma negra que tiene la tapa porque si se cae si llega a salir un poco de agua todo lo demás muy bien cabe mucho líquido
