BlenderBottle Blender Classic Loop Top Shaker Bottle, 28-Ounce 2-Pack, Pebble Grey

I used it few times, i shook it vigorously and never had leakage. Top 👌

this is easily the best blender bottle style I've had. It closes much more securely than some of the more recent styles.

My family uses these all the time. We have always bought the ones that are the standard clear and after a couple months they always turn to a tinted red as some of the BCAA's that we put in them are red in color. I hate that! So we tried these out hoping they wouldn't turn red and after ~ 5 months they haven't turned red in color. So they are my new favorite shaker bottle. They are just as good or bad as all the others in terms of leaks and all of that. If you thread the top on correctly and tight they generally don't leak, maybe a drop or two but that's it. I wash them after each use in the dishwasher and they hold up great. I'll be gradually phasing out the clear ones for these tinted ones so that they don't all have a red color to them.

at first I did not like the little handle on the lid as it makes cleaning a bit tougher, but now I am happy with the feature. it is nice to be able to grab the bottle with a finger or two. especially useful when returning home from the gym and unlocking door with keys.

I put my pre workouts in this and I put my coffee to go every morning in it. The ball breaks up powders real nice. You'll definitely know when you have a crap bottle when you put whatever liquid contents into it and go for the classic shake, and boom, all the stuff spills out on the counter, or your clothes. This blender bottle does the job in regards to keeping the contents in it. In addition, it is a great price for 2 of them as well. Don't get lazy and leave remnants in it and let it stink up the bottle.

they were great but no matter how much and hard we cleaned them we COULD NOT get the smell of protein shake out of them :( ended up getting rid of them because they stunk so bad
