BJPKPK Insulated Stainless Steel Tumbler, Coffee Cup with Lid and Straw, Double Wall Vacuum Travel Mug, Powder Coated Leakproof Tumbler Cup,Oasis

I absolutely loved this tumbler. It keeps cold drinks at the perfect temperature (I don’t really drink hot beverages, so I can’t say much about coffee or anything like that). I’ve left it in the car under the sun with ice and water, and it stays just the same. It doesn’t spill, no matter what’s inside, and the lid is sturdy and secure—it doesn’t come off easily.

Keeps my drinks at a great temperature, easy to hold, no leaks and is made quite well. No complaints here✓

My absolute favorite cup. I love the colors of this cup and I love how it feels in my hand. It is easy to hold and carry. It keeps my drinks hot for literally hours.It is leak proof and has a cap to cover your straw when you're not drinking it. It is well worth it.

Wife loves it, not cheap made, comes with metal straw

I liked the BJPKPK 30oz Rambler except for one tiny detail. As you can see from the first picture, I wanted to test a few different styles of Yeti, against each other and a cheap substitute. (BJPKPK, Sunwill & Sursip, & this) The Yeti is superior in build quality and ergonomics. It is more comfortable and fits the hand better (mine anyway). From the pictures you can see that the Yeti can be used with a straw or sans lid. The Sursip can also be used with a sipping lid! I barely use a straw and the Sursip came with two as it came with two lids. My dad has the Yeti and was crushed when he lost his straw and found that Yeti makes getting a replacement cost prohibitive. As for the straw itself, the Yeti is larger and better in every way. My dad also had to buy a cleaning wire for his Yeti. The Sursip comes with one. As for the temperature test. Once again, all the Yetis are superior. But how much is what matters. For the first few hours they are nearly identical, and then after that the Yeti is again far superior at keeping liquids colder for longer. But, if you left them both out with liquid and ice overnight, they both will still have cold liquid in ice come morning. As for the lids? IF you want a tight no leak fit. Get a YETi!Personally, I would have kept the BJPKPK 30oz Rambler except it is just too big for my hand.Some people are Oakley ~ Nike people and some people DGAF about brand image. I decided to pay half as much and keep the Sursip as I DGAF. Just my Joepinion. For me, close enough is the same. Obviously, you are a different person with different wants and needs, and I hope I gave you the ability to make a wise choice for yourself. Aloha Joe Jr.As for the coffee mugs (Sunwill) I wanted to supersize my morning coffee & choose a 14 oz Yeti mug to start. Yes, it does take 14oz of coffee with room to fit the lid on it, as do they all. The Yeti is superior in build quality than the Sunwill (& the Sursip/BJPKPK 30oz Rambler). But ergonomically, I like the size of the 10oz Yeti. Instead of gaining the extra 4oz from height, Yeti gained it in width, as in 100% of the 4oz. This made the cup unwieldy and awkward to transport, and I was uncomfortable lifting it in front of my laptop. The handle of the 10oz Yeti fits the fingers better than the Sunwill, (wider and more material used) making transport from coffee pot or room to room more comfortable. As for the temperature test. Once again, all the Yetis are superior. But how much is what matters. For the first hour the heat retention is identical (nearly), and then after that who cares if the Yeti keeps it hotter longer? It is already too low temp for coffee. As for the lids? IF you want a tight no leak fit. Get a YETi!For me, the 14oz Yeti model is just unwieldy. And the Yeti Rambler just can't justify the price even though it is hands down better in every way. Just my Joepinion, aloha Joe Jr.

Never has a cup fit so seamlessly in my life as if it's always been there. Perfect size, and keeps my iced coffees cold longer and helps the ice not melt and dilute my drink. Absolutely love this cup and the dual lid option.

Lids are very loose on the cup

Absolutely gorgeous love the color. Definitely keeps my coffee nice and hot. I was out in freezing temperatures the other day with that at football practice for my son and my coffee maintained a nice hot temperature. I love that. It comes with two lids and the straw highly recommend will be buying another.
