    Great surprise

    It hadn't really occurred to me to buy a glass bottle, especially as I tend to be hard on things, but I got one as a Mystery Item and I love it! There is something...luxurious about drinking through a glass spout.

    First of all, how do you guys know which colors I like?

    I take a particularly sticky collagen supplement twice daily, and although I like a 32 ounce bottle in the morning, this smaller size is perfect at night.

    I haven't had the problem some people mention with having the stuff goop up the top, even though it is practically wallpaper paste. I don't fill it all the way, and have started simply rotating my wrist, as is recommended somewhere on this site, rather than the over the shoulder bartender style. It seems more effective, and better contains the catastrophe should I neglect to tighten the cap fully.

    As I said, I'm hard on things, but despite being surrounded by limestone tile and granite counters, no shards yet.

    I do go to the trouble of completely disassembling it, including the silicone sleeve and the little gasket in the top, and putting all the components but the bottle itself in the top silverware rack of the dishwasher. Well worth it, as it's stayed fresh as a daisy, and no signs of deterioration, despite near daily use and extremely hard water.

    Another fine product from Blender Bottle!

    Great product!!!

    I purchased my blender bottles last year in AZ at Sprouts and they are absolutely perfect! I was so excited when I found them! I really like the glass aspect and if it could be leech proof glass this would be even better since I sometimes don’t have time to clean them, being a busy mom. I am buying one for my son to start school this fall as well and it makes me feel so much better knowing they are not made out of plastic. The shaker is great but he tends to play with it and stretch it out (lol). luckily they keep their shape well even in kids hands. 5 stars all the way. They fit perfectly in my new rav4 cup holder and literally have no complaints. The seals could be a little easier to remove and clean but then again I think it would compromise the leakproof technology. So glad they never leak (unless you forget to put the little silicone stopper in the top). Thank you guys for making such a great product that is safe for the whole family.

    Good but not perfect!

    Good solid product that seals well, no leaking issues here. Like the glass and plastic free aspect, as well as silicon protection.

    Room for improvement --
    1) Difficult to put in protien powder with slender design -- needs a wider mouth to accomodate protien powder scoops.
    2) A little clumping of protien powder inside the lid, but nothing too serious.
    3) Top rack dishwasher safe is fine, except with the height of this, it will never fit in a top rack. Needs to be bottom rack safe.

    Hi Kevin,

    We appreciate the feedback, we will pass it along to our teams.

    Leaks like crazy

    I just purchased this from BB&B and was so excited to have a glass shaker bottle. Every time I have used it, it starts spraying the contents out every time I try to shake it. So disappointed!

    Just great as it will barely never smell ;-)

    I wanted a Shaker without plastic, that simply does not smell if you forget it in your bag. It goes perfectly in the cup holder in my car. I like the design.
