It is a fine shaker bottle for a nice price. Nothing more to say.

I use these shakers every day and they're great. I like the filter they come with.

This is an excellent cost-effective shaker cup. The grid does an excellent job mixing the product with little loss to clumping/sticking. I mix protein powders into white and chocolate milk and also the clear whey isolate with water. Finished mix is up to expectation. They're inexpensive enough to throw one into my cart every couple months to have extras. Haven't worn out the first one yet, though.

Best bottle I have ever owned by a mile. I put protein powered, pre workout and creatine into this bottle and after 30 seconds of shaking I can drink it all without any lumps and it helps massively. I would 100% recommend this bottle even if it was 5 times the price 

I don't like the grid design. Protein gets stuck in it and comes out in clumps when I'm drinking it. Going back to the metal ball

The bottle seems to be pretty sturdy, the marks on the side are convenient for measuring. The shaker is just a plastic sheet that sits at the top with a bunch of little hexagon holes in it. The shaker doesn't sit well when being shaken, it flips and turns and has to be pit back into place. There is also a very weak seal where the lid meets the bottle, and unless you tighten it with all your strength, there will be a slow leak. I have 2, and the problems are identical for both.

It works well, doesn't leave clumps (however I haven't tried with the clear whey yet, and according to reviews that product has trouble mixing). Although, I wish there were more marks on the side for volume. I'd like to be able to tell where 6-8 ounces is so I can get the perfect mix first try instead of guessing when trying to mix the protein powder.

This is a good bottle. It doesn’t have the shaker ball in it, but it does have a mesh grid to avoid protein chunks. Either way, I didn’t have any issue with clumps remaining

I’ve never had a shaker so I don’t have any others to compare it too but this gets the job done with the clear whey isolate. That’s all I use this for. 

Screen filter for shaker works great and is easy to clean.
