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

This is my favorite protein shaker cup. I’ve had dozens of the plastic versions and have ruined them by leaving them in the car in the summer. There’s only so many times you can soak plastic cups in the sink with bleach and hot water and soap before you start worrying about the plastic bleaching into your beverage. The stainless steel is great. There’s no smells and it’s very easy to clean. Works great as a water bottle and keeps your eyes cold for a long time I would order another one.

This should be the standard for any protein shake cup! It has seals around both the lid and the pop-up mouthpiece with a lock feature so if you set this down while you’re at the gym, you can have peace of mind, knowing no one was able to drink from your cup or open it up and put anything in it!

This is hands down my favorite shaker. Very easy to clean. The best part is the inner seal has a pull tab which makes it easier to pull out for cleaning. Blends protein powder smoothly. You won't be dissatisfied!

It blends quickly and easily, and it cleans even easier. Nothing sticks to the stainless steel inside.

I have always use blender bottle and switched to the stainless steel bottle from the plastic bottle. Well worth the cost for the price, especially compared to other stainless steel drink ware. Definitely keeps your water, protein, pre-workout, or hydration cold for a long time. The hook lid makes it easy to carry with a finger if you have something else in your hand or have to grab something. This blender bottle is easy to use and has everything function a blender bottle should. Only got 4 stars because I would like an option for a non locking drink lid.

Sturdy, and keeps things cool!

This cup is one of the more costly blunders of my life. Not that it's a bad cup, in fact, it's amazing. It just makes all my other cups feel cheap or like they're overcompensating. My wife now refuses to drink out of anything else and the bad news is I kind of agree with her. We love these so much we actually read the care instructions and hand-wash these out of fear these will be destroyed by our appliance. Buying more and probably giving away our other vacuum steel cups.

Should you buy an insulated shaker bottle? Yes! They clean up better, and if you forget to clean them, they do not stink as bad. Also, if you drink protein throughout the day, this is key, as it keeps the liquid cool. The shaker bottle seals well and does not leak, and the lock on the flip-open top is a nice, premium-feeling feature. As an experiment, one day, I made a protein shake at 10 PM and took it to work with me the next day. I drank the shake (after re-shaking it) at 11 AM, and it was still cool! That is excellent functionality. Finally, it is priced well.
