Blender Bottle ProStak - 22oz Protein Shaker Cup Water Bottle incl 150cc and 100cc Jar,White,650 ml

Highly satisfied with it! The 22oz capacity is perfect, and the additional 150cc and 100cc jars are incredibly convenient for storing supplements. The sleek black design is both stylish and functional. The secure lid and efficient mixing ball make it my go-to shaker for protein shakes. Overall, a practical and well-designed product.

This is a great piece of design. I've used shaker bottles for years, but always the basic classics. I wanted something better at mixing the protein, with the ability to bring spare powder for a post workout drink, but never found one that suited.I've tried others, but they always missed out on critical details, such as having a powder compartment that was either too small, or didn't have a separate lid (they attached to the bottom of the drinking compartment, which left powder all over the bottom, which was a pain for later use of in a bag)But I can honestly say, this is the best of every aspect.It's got great build quality, the latch on top makes for easy one finger carrying, the mixing ball does a good job at mixing (I use a 2 scoop 300ml water mix and it does fine) and the lids on the powder compartments are great. The 2nd compartment even has a pill tray (which I don't use), but the design is great. The pill tray doesn't rattle around, but screws into the inside of the lid for the compartment. They've really thought of everything.Only qualms so far are the smaller drinking section (which i find as a plus as well, as it isn't excessively big) but if you were to mix much more than 350-400ml, it wouldn't give much shaking room. But not many drinks need that amount of fluid. And the mixing ball is a bit annoying to fit on a drying rack, because it's a rotating piece of wire that collapses when pushed, it wraps around cutlery and the drying rack, which can be a pain.But other than that, I'd really highly recommend it if you are a regular gym user

Firstly the quality of the product is great. The additional containers screw on well, aren’t too tight while being tight enough that they won’t fall off and the whole package just feels sturdy...I’ve been using it for about a month and it doesn’t feel like it’s letting me down for some time.The shaker ball inside is very cool and does a great job in mixing protein powders etc in with whatever liquid you bang in there. It does sound like you’re making a cocktail when you’re shaking it so you will get requests for Bloody Mary’s and Sex on the Beach so be prepared (personally there’s not enough room in my work bag for all the bottles).At £12 I did wonder if it was worth the punt but it genuinely is as it’s a quality product that feels like it will last for years.

The main bottle and the extra containers are very well made and do not leak. The large container can hold about two scoops of protein powder and the smaller can hold one scoop. Very handy if going away for just the weekend or for taking to work. Only issue is it does seem to take a lot of shaking for the blender ball to help dissolve all the powder and some dry powder can get stuck around the rim of the drinking spout. Other than that it works very well. Also BPA free for those who care :)

Great bottle for protein shakes. I wanted a smaller bottle as my other one was only a third full and it felt like a waste of space in my bag to be carrying it around. I put 250ml of milk/water and two scoops of powder and there is still plenty of room to mix it. The little pot that attaches to the bottom is a great idea as I can put my powder in there, take it to the gym separately from the liquid and then mix it just before drinking so its fresh. It would be good if the pot was slightly bigger as the powder only just fits in, but then it comes with two, so I can take them both with me if needed. The metal ball thing seems to work as it only takes a few minutes for the shake to be smooth and free of lumps.

Good size for training without the storage unit. Sturdy in the bag with my gear. I prefer to hand clean ready for the next use instead of the dishwasher. Easy to clean especially getting those small bits of mixture around the lid area and base of shaker.My only complaint is that it does not cater for small powder requirements i.e. pre work-out powder. The storage unit just too big for a small scoop. It should have a divider (plastic half or quarter, like the pills compartment) of some sort. Got to carry a small bag

The product works very well . the seal has not yet leaked and ive been using it for months and the compartments show no sign of ware . the metal ball inside used to blend the protein and avoid lumps as not distorted at all and still functions the same getting most large lumps of protein . Most being the key term here , i cannot give this product five stars for 3 reasons the first being that after a month the small compartments found on the bottom of the cup became hard to open . I am by no means weak and yet i still have to really give it some to get one of the compartments open . this is a small problem however as there is a second compartment and i find it hard to have a use for both of them anyway often leaving one compartment at home . the second problem is rather minor and probably just a personal thing but i cannot stand any lumps in my protein shake and though this gets most of them it does not get all and i still find myself occasionally gagging due to a large lump not have being broke up. The product is easy to clean on the surface allowing you to remove all visible protein shake from the inside of the cup however if the cup is not washed within 5 hours of use the cup after a while begins to smell like a bin and honestly makes me sick i don't know whether this is the plastic or simply unavoidable as every other protein shaker i've used also has the same problem. The rest of the product however functions perfectly the neck of the lid fits perfectly in your mouth and leaves no residue on you at all and the detachable compartments make it easy to take small items that you may need . Overall an excellent product however some improvements could be made to the blender design.
