BlenderBottle Classic V2 Shaker Bottle Perfect for Protein Shakes and Pre Workout, 45-Ounce, Black

I like the product concept. However, It was listed as 20 ounces. I bought 4 of them total. I was disappointed to find the high measurement mark was just 14 oz. I corresponded with customer service and they assured me that it was 20 oz to the top of the rim. I tested this theory and UNTRUE. It did not even hit the 18 oz point. In conclusion, good product just not truthful in sizing.

Im not sure when BlenderBottle made this change, but its wonderful - the bottom of the bottle is concave, so protein powder doesnt clump up in the corners anymore. (It sits flat, theres a lip around the outside.) The bottles now mix really well, and get clean in the dishwasher. Good stuff!

I used this product at college for protein shakes when I didnt have a blender and it made shakes very easily and broke up chunks that other shaker cups had not been able to.

I bought this bottle primarily for my protein shakes. Ive been using a blender but I realized that puts too much air into the protein shake, which I heard makes it harder to digest. This blender bottle has a wide mouth good for mixing powders or adding ice. The lid is nice to drink from and stays closed well.

Lid stays closed no matter how hard you shake

nice product, good quality , best choice

Works great, no leaks, quite compact, easy to drink from and no unpleasant odors. I usually fill to about the 10oz mark and it is fine to that point. May be difficult to shake a larger quantity but not a critical flaw. I think the 28oz bottle would have provided more options.

I use a shaker bottle nearly every day and BlenderBottle shakers are among the best I have tried. The spiral metal whisk-y ball does a great job of mixing up your drink, the bottle feels solid and secure when shaking, it is comfortable to hold and the spout is a good size for drinking out of. Overall this is a pretty good shaker with only a couple minor issues. Pros: * Good size - not too big, not too small. There is nothing worse than a shaker that is way too big, leaving too much empty space. Similarly, bottles that are too small dont feel safe or secure when shaking. The BlenderBottle hits that magic Goldilocks zone of bottle size. (At least for my use.) * Leak-free lid. Both the lid and the spout cover provide good, safe seals. I dont have to worry about my drink flying out as I am shaking the bottle. The spout clicks into place securely and isnt loose like some other brands. The leak-free seals are very important to me - more than once I have had to clean up sprays of drink when the seals on other bottles were too weak. * Solid, sturdy construction. The plastic is nice and thick and provides a good sense of quality. These bottles are built to last. * Rounded base. The V2 bottles have a rounded base inside. This means your powders wont get stuck in the corners because there are no corners. Couple with the shaker ball, this means more of your powder gets mixed in. * Drain hole in the base exterior. With the rounded bottom, the outside of the bottle has an extra extrusion so you can sit the bottle on your bench without tipping over. This extrusion has a drain hole so after washing you dont end up with a pool of water in the base. This is a great feature IMHO. Cons: * The drain hole in the space could use a few friends. If you sit the bottle at an angle, (for example, when loading the dishwasher) the drain hole isnt as effective unless it is at the lowest point. Adding a few more drain holes would make the drainage more successful in these situations. * The spout seal doesnt click in with quite the same, confidence-inspiring CLICK! of the V1 bottle. It still makes a great seal, but the CLICK! of the V1 seems to inspire more confidence. * The measurements on the side of the bottle are not as effective for me. I typically mix up 8oz drinks. The scale on the side of the bottle jumps from 6oz to 10oz, meaning I have to eyeball where 8oz should be. The V1 bottle has 2oz increments, but the V2 has 4oz increments. Also, the V1 bottles have lines marked every 2oz which helps get your levels right, but the V2 just has numbers with no marked lines, so even when measuring 10oz you have to guess where the line should be. I am not sure why they would have done this because it makes the measurements more difficult than they need to be. The only significant drawback is the lack of useful measurement indicators. Apart from that this is a nearly perfect shaker bottle. Easily streets ahead of any of the other bottles I have tried over the years. I already have two and am thinking of buying a couple more because I use these two so often. You wont be disappointed buying one of these!

Love the size wish there was bigger.

Works great! Much cheaper than other brands. Ive had it for three months now and hasnt let me down even after numerous washes in the dish washer. Definitely a recommended purchase.
