Great water cup
Size: 40 Ounces, Color: Peony, Size: 40 Ounces, Color: Peony
Love this water cup! I like to use it around the house. I like how much water it holds, because I drink a lot of water. The color selection of these cups is really good too; I went with the peony cup. It is very vibrant and bold in color. I would say as for on the go, they can get pretty heavy if walking with it full of water, so maybe not the best choice if you are travelling by foot and carrying it. One thing I will say is that this keeps the water VERY cold for a long period of time! Definitely good in that aspect. The handle is very pleasant to hold too, as it has a soft silicon-like material along the handle, and feels very sturdy and thick. I do wish that the straw was more clear, but that isnt too hard to replace. If you want a water cup for around the house, I would reccommend

Great purchase
Size: 40 Ounces, Color: Rose Quartz 2.0
I was a Stanley skeptic. I couldn’t understand what the big deal was or why the internet was freaking out. I saw the video of the Stanley cup surviving the car fire (and I think the ice was still inside). So I tried it.
I drink SO much more water now! I love decorating my Stanley with all the fun accessories and it holds a nice amount of water. It feels durable and good quality.
I’ve had my Stanley for a year now and I’m even considering getting another so I can have one while the other is being washed. They are easy to clean as well because of the metal inside.
There are two issues I’ve had since I got the Stanley cup. Once it was dropped, and the lid broke. Easy to buy more so not the biggest issue. The cup survived the fall just fine, not a mark on it.
The other issue I keep having is my lid gets stuck and becomes hard for me to open sometimes. I have a bad thumb and wrist so often I have to have my spouse open it for me.
It keeps my water cold all day. If I put ice in before I go to sleep it’s still cold in the morning. I love these cups and would recommend them to anyone looking to drink more water. If you like your water bottle you will drink more water and want to bring it with you.

Very strong and cute tumbler
Size: 40 Ounces, Color: Rose Quartz 2.0, Size: 40 Ounces, Color: Rose Quartz 2.0
Great quencher to get. I got this for my self and I love it so much. It's super cute and the color I got is a light soft pink. The size is big which is great since I like having enough coffee to last me all day. It keeps my drinks cold and warm or what ever temperature it is for a good amount of time which is great for anyone who is out for long periods of time. The quality overall is very good. The handle is big, comfortable and easy to grip and the quencher fits perfectly on my gym bag. Only downside is that it did get a smudge on it after I removed the paper that it had on the bottom. I tried removing the smudge it feels sticky like glue but it didnt get removed so I had to put a sticker over it to cover it up.

Great Water Bottle!
Color: Off Road, Size: 30 Ounces
I was looking for an insulated water bottle that would actually fit in a standard cup holder. I decided to try the Owala FreeSip Sway Insulated Stainless Steel Water Bottle. Upon receiving it, I noticed that it felt solid in my hand. The mechanism worked very smoothly with a simple button press opening the lid. Once open, you can choose to either use the included straw or tip the bottle and drink from the chug spout. In addition to it fitting in my cup holder, I needed it to be leak proof. This bottle is leak proof, and the spout can be locked by engaging a lock in the back. The rugged flip handle is also a convenient way to carry the Owala when it's not in the water bottle holder on my backpack.
I hand wash the body of the bottle, but the top disassembles easily and can go right in the dishwasher when I want a deep cleaning. The bottle has a wide opening, so it is very easy to clean the inside.
This has quickly become my favorite water bottle due to its ease of cleaning, good insulation, ability to fit in my cup holder, solid construction and materials, and the option of using the straw or chug spout. I have the 30 ounce bottle, but I am going to be picking up a 40 ouncer also. You won't regret purchasing one!
I have used the bottle for a couple of weeks now, and here are my observations: It has gone on two camping trips, and it has proven to be durable. I have placed the Owala on its side on my passenger seat (just to test it...it fits perfectly in my car's cup holder!). It did not leak a single drop on a long road trip. On my camping trip, the water in the bottle was still ice cold the next morning, so it keeps cold beverages very cold!
