BlenderBottle Sport Twist Insulated Stainless Steel Shaker Bottle with Wire Whisk, 24-Ounce, White – Protein Shakes & Hydration for Athletes & Fitness Enthusiasts, Easy Mixing, Keeps Drinks Cold, Twist Cap

Best blender bottle. I really like the stainless steel on the screw cap. It doesn’t leak.

This was a great buy. Quality construction, super durable, just a great product. Recommend 100% hands down.

My husband likes to take his protein shakes to work with him in the morning. I bought this for him so that when he inevitably leaves it in a hot car all day it doesn’t get as nasty as a plastic blender bottle would. I wanted this to stay nice looking for as long as possible. He choose the screw on cap so it doesn’t open on accident. The seal on it is great, there’s no way to accident open it. The quality of this bottle is pretty good. It’s not as thick or heavy as I expected it to be, but it is durable and pretty light for the size. The only downside to this bottle is that is recommends not putting the stainless steel cup part in the dish washer. I think it would probably be fine, but I don’t want to risk it.

looks nice, feels like quality, worked really well breaking up whey protein clumps

Would like it to be a bit bigger but most bottles seem to be about this size or massively larger and no in-between so that's more of a complaint about the industry than this cup. Screw open lid is a bit annoying but better than having the pop open option and slinging stuff all over my car while mixing. Materials seem high quality.

I like the fact that closes tight with no leaks, and that you open the drinking knob so easily (1/2 a turn)

The bottle is very well made. The insulation is excellent for keeping protein shakes ice cold. Also, it's much quieter than some other blender bottle products. However, the bottle does require more cleaning than other bottles, primarily because of the rubber ring that wraps around the cap. This needs to be removed when cleaning because residue from protein shakes can get trapped underneath and lead to terrible smells over time. Otherwise, this is one of the best shaker bottles I have ever used. I recommend this bottle if you don't mind spending a few extra minutes cleaning it after you use it.

Keeps liquids cold and is easy to clean. I like the twist cap and the handle.
