BlenderBottle Radian Insulated Stainless Steel Shaker Bottle, 26- Ounce, Matte Black

I own a lot of bottles. I wanted this one because it is stainless and I wanted to keep my drink cold. It hit the mark. My drinks are cold for hours. I use ice, and it keeps well. It is comfortable to hold. It took me a minute to get the seal right, so it leaked for a little bit, but I got it in there and fit comfortably. I hand wash my bottle, and it is easy to keep clean. I would highly recommend this bottle.

Bought the insulated bottle because I wasn't going to drink my shake for 5+ hours after making them. Bottle keeps the drinks nice and cold and fresh. Easy to clean the stainless steel inside and is perfect for everyday use. Be careful when you close the lid though. If the cap isn't properly aligned, it won't close correctly and you'll spill your drink everywhere when you're shaking it... yes I'm speaking from personal experience.

Perfect for keeping your protein shakes cold. It'll keep it cold for 4-6 hours depending on your environment. That's plenty enough time for me to finish the drink. The lid has a rubber o-ring you can remove to clean it's nooks & crannies. The lid is plastic & the body is metal.

Just have to screw the cap on correctly or it will leak like crazy, and it is not at all intended for hot beverages--not thermos quality. Overall, it's better than going through ten or more plastic blender bottles. You save money for the long term, but I suggest getting a different agitator to make it more silent.

***update*** Been using this for over a month now and it started to stink. I couldn't figure out where it was coming from till today. You have to deep clean the small mouth cap! It comes off the loop. There's no way I found to remove the rubber seal in there. But guck builds up! Use a metal skewer wrapped in paper towel with soap to get in there! Couldn't believe what came out! Design flaw?!?!Was a bit hesitant to try this. Most of the steel shaker cups I've tried suck. They leak. Usually at the cap where plastic meets steel.Don't get me wrong - it has spilled on me a few times. But I've noticed its always a sealing issue, usually the top mouth cover not seating correctly. I usually try to get into the habit of closing the mouth cover while the cap is off. To make sure it sits correctly. Pro Tip - spin the detachable loop a few times before shaking. If it spins freely, the cover and cap are seated correctly. If not, good chance it may leak.What I do like is the design. The shape allows me to pick it up and not drop it. Unlike all the smooth steel shakers that are designed like coffee travel mugs. That design feature helps. Also the rubber cap to help tighten it closed is super helpful. I like the detachable loop to make sure it's closed and also so you can hold the drink any way without the cap strap getting in the way. The inside markers are helpful. Finally, the see through top is a nice touch. You'll know how much liquid you have left. Overall, I feel it's a good design for a good price.So to the poster who said it constantly leaks - I agree. That's why I was hesitant to try this. But I've noticed that most times its user error for the leak. I'm keeping this! Super helpful my supp stack and everything I use!

This is hands down the greatest bottle ever made for making smoothies and shakes. And it is also fully insulated. You cannot miss with this.

I've had this bottle for more than a year now and I'm getting a second one. I'm the kind of person who enjoys finding the best product and this is quite possible it as far as sport drink shakers are concerned.Things I liked:- The bottle and lid are well designed - you can flap the lid back so that it doesn't drip on you when you're drinking- It's easy to carry thanks to the carry loop attached to the lid- It's easy to hold in one hand- The vacuum insulation means that cold drinks will take much longer to start developing bacteria in it. If you've ever forgotten to clean your shaker, you know what I mean.- It has notches inside for measuring the amount of liquid you pour inThings I didn't like:- The blender ball is very loud in this steel bottle, so I took that out immediately. However, I didn't really notice a big difference without it

When making the protein shake in the morning, it is easy to take the top off and put the powder in. When you actually drink from it, it is very nice that the strap that secures the lid can be flipped out of the way so that it is easier to use.
