    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.

    Really want to love it...

    But like many other comments, mold is a problem, as are the non replaceable gaskets and cap. Maybe planned obsolescence is part of the marketing scheme, but I'd much rather invest in the bottle and buy parts when they need replaced. The bottle itself is bomber, but will end up just another insulated mug and I'll find another option unless BlenderBottle starts supporting with parts.

    We appreciate your feedback. Our customer service team would be happy to provide some helpful cleaning tips for mold. Please reach out to customerservice@blenderbottle.com.

    Very well made product

    Make sure to screw the top on well so you don’t spill when shaking. I usually fill about 3/4 full, shake, then add more water and finish shaking to reduce foam. I typically have some powder congeal at the bottom that just doesn’t seem to get caught by the ball. I also shake the bottle periodically throughout my workout because the plastic top doesn’t seem as well insulated as the metal bottom.

    Good and Bad

    I have been on a quest for the best stainless steel water bottle and in my opinion it is the blender bottle Strada the only problem being that you cannot get replacement lids.

    So when the Radian came out i was excited/hopeful because replacement lids are available! But as many have said if you do not get the lid on JUST RIGHT it will leak...

    I wish we could get replacement lids for the Strada because it is honestly the best bottle I have ever used

    BUT blender bottle does do a good job on both stainless steel options

    Strada and Raidan both have lids that are dishwasher safe which helps with 'mold' the bottles are VERY tough I have dropped them multiple times ands never had a broken lid or bottle my Strada has a small dent but still stands and works perfectly. They hold the cold VERY WELL I always ending up dumping out ice in the morning when I make fresh ice water. I use flavor powder in my water so I aggressively shake these bottles multiple times a day and no issues with leaks IF I have the lid on straight.

    ALSO FOR ANYONE LOOKING AT THE ARCTIC BLUE it is actually white. I would have thought that it was white and I had accidently ordered or received the wrong color but the lid does not have the gray strap like the white bottle pictured so it is indeed the arctic blue...

    We appreciate your feedback for our products. While Strada lids are not currently available on our website, they can be ordered over the phone by calling (385) 293-3935.
