I have owned for 1 month, leaks for all liquids from between the threads of the bottle. Don't spend your money on this. I have followed cleaning instructions of top shelf only or hand wash.

The Contigo 28 Oz. Fit Shake & Go 2.0 Shaker Bottle is perfect for the Gym. That is when I use mine the most. I also take it to work with a green smoothie in it, for a quick, healthy pick me up in the daytime. It is a nice size and can hold 2 servings (for me anyway), of drinks, or shakes. The Contigo 28 Oz. Fit Shake & Go 2.0 Shaker Bottle is the best for on the go, long car rides, work breaks and lunch, and the gym.

This shake container works pretty well. I like the design because it is a good size to fit in cup holders and not too big. I also like the way the top secures and opens. It is nice to use for mixing my drinks for the day.

I use this waterbottle on my mountain bike rides and it holds up well to the test. The most important thing to me is how well the lid stays shut. On long mountain bike rides in100 degree summer heat, the last thing i want to do is reach down to an empty water bottle with a lid that opened on the ride. This one has stayed shut over several hundred rides. Fantastic!

This is a good size water bottle that does the job it's meant to do but I don't like the plastic material - I would prefer reinforced. It does the job but I'm not sure it is durable. I'll keep tyring and see.

This shaker water bottle is exactly what I was looking for. It's durable and leakproof, which is great for when I toss it in the car! I love that this has a handle to carry it as well. It is great for my protein shakes, and I've even used it for water. This is easy to clean, and I have no issues with throwing it into the dish washer. I definitely recommend this shaker.

I use this every day. Never thought I'd like it so much. Little mixer ball works to dissolve my vitamin mix better than anything I've tried. Clumps be gone. I love it and recommend it. Anyone who takes vitamins or supplements this is a must

Having tried many shakers, this one is really nice. The lid closes tight so no liquid spills or drips out. The hook is a little big, but it is easily clip on many different bag straps for easy carry outside the bag. The contents mixes well with the added shaker ball.

This is by far one of my favorite brands. All of the water bottle or liquid containers in our home are Contigo from the adults to the kids. This is a really great shake and go bottle. I really like the oversize clip for when you're working out and the cap helps avoid leaks. The only thing that bugs me is the plastic shaker. Otherwise this is an amazing product!

This is a great shaker bottle. Does everything I need it to do and holds and seals liquid in great. It has a great little handle as well and the shaker ball seems to work really great also. Very nice product
