BlenderBottle Strada Shaker Cup Insulated Stainless Steel Water Bottle with Wire Whisk, 24-Ounce, Mango

The quality of this shaker is impeccable. It keeps drinks cold for 16 hours + and prevents ice from melting for a solide 6-8 hours. It's sturdy and the lid closes tightly so there's no leakage. It's super easy to clean, doesn't have a metallic taste and doesn't leave an aftertase of the drink you had like some other shakers or stainless steel bottles. It's easy to carry/transport as it fits in a car cupholder perfectly. I'm going to buy a few more. Best shaker I've ever owned.

It’s smaller than 740 ml. The cup will be full at 590 ml just like the third picture.

以前同じ物を持っていましたが、ヘビーユーザーなのであちこちガタが来てしまい、リピです。 これの良いところは保温と保冷ができるだけでなく、飲み口がロックできるので、何かに引っ掛かっても飲み口が開かないところです。 但し、初代？を２、３年前に購入したときは2000円ほどだったのに、今は倍の4000円。 あまりお高くなるようだったら、次はないかもしれないなぁと思うと残念に思います。

beautiful design, works well, easy to clean!

tl;dr: great shaker cup that both mixes and cleans extremely well. I got this to use with protein powder and wanted something that was above all easy to clean and that could mix well. I'm happy to report that this does both of those things well. The protein powder I use is notorious for being "clumpy" however when using this shaker I've had a consistently smooth mix which has been pretty much perfect (at least for my tastes). Then when it has come time to clean it's been an absolute doddle and usually only requires a quick rinse with hot water, no smells, no stains. The markers on the inside of the cup make it super easy to mix up the right amount of powder too so that's a nice touch. I personally love the style of the cup too, it looks understated yet has a certain charm to it, though I appreciate that is very subjective. The lid goes on very easily (once you work out how) and seems to be very secure, no leaks so far! The only small gripe I have is with the flap, it seems to be quite stiff on my unit and I'm never sure if it's secured properly or not. I do worry that over time it may not sit correctly, but I guess time will tell!
