Strada™ Stainless Steel Blender Bottle

I wanted to wait and use this for a while before giving a review. I've had it for about 2 months now, and i couldn't be happier. I use it mainly for my water intake at both home and work. I only ever used plastic shakers in the past, and while I liked them, they are not very good at keeping liquids cool for any extended period of time. I bought this as i was going with my son to his school's camp for a week in hopes that I could be out all day and it still remain cold. Well, it did! I work outside all day for my job, and despite the outside of it feeling warm, the liquid stayed very cold. This is while it was in direct sunlight. I use it all day long for my water needs. I bought the red color bottle, and it looks great. I have not used it for my protein shakes yet, but IO have no reason to believe it wouldn't keep those cold as well. I like the lock feature, and it is stupid-easy to use. In fact, having the lock feature helped so that the lid wouldn't pop open while in my backpack. I will probably purchase a 2nd one in the future. This product is well worth the money!
