    Love this bottle!

    I love this bottle so much, that I ordered two to replace the one I left behind on a job site a year ago.
    This particular bottle is the ONLY one that will actually “get me to drink water”!

    The stainless steel really makes filtered water taste the best. And it keeps it cold!

    It’s my bestie!

    Great for cold drinks and looks cool, but leaks when you shake it..

    I wanted this one to be my favorite, but it leaks every time I shake protein in it. So I have to use a paper towel around the outside from having the shake mix get all over the floor. It does keep drinks cold for a long time. I do like the way it looks and the handle thing is nice. The bad leak trumps all the good though.

    We are sorry to hear that your bottle is leaking. We do have a leak proof guarantee, and it sounds like this may be covered under our warranty. Please file a claim here: https://www.blenderbottle.com/pages/warranties-returns-exchanges.

    Mildew/Mold grow on the silicon gasket and interior cap

    Mildew/Mold WILL grow on the gaskets of the lid and the cap. I have 2 sets, both have embedded mildew/mold growth. Will not come out. BlenderBottle will not sell gaskets anymore, now you have to spend $$$ to get an entire lid/cap/gasket setup (even though you just need 50 cent gasket)
    Does stay cold! However, the growth is a REAL problem. Leaks too.

    Bottle leaks a lot

    I like the bottle overall since it keeps my drink cold but the biggest issue with this bottle is that it leaks :(

    Leaks like Niagara Falls.

    This shaker is awesome if you like showering in whey protein. I was able to get a refund from the original vendor but after reading these other reviews I see this is a common problem with this model. I repurchased a plastic version, guess what. It seals. Unfortunately I did not have this model long enough to experience the mold issue.

    We are sorry to hear about your bottle leaking. We do offer a limited lifetime warranty on all of our products. If you submit a claim here our warranty team would be happy to take a look at it.
