Mixes my powders together well but I tried a banana and it mashed but had chunks in, could be me not shaking enough though.

I bought 3 of these as I needed to replace my old shakers and the reviews for this are amazing. I watched a bunch of demos on YouTube etc too, seeing it smash through whole bananas, turning them into a smooth puree. HOWEVER, although everything about this shaker is better feeling, less hassle and more ergonomic than any other shaker I've used, the big problem is that it doesn't actually work. I find myself shaking my protein shakes for twice as long as I used to with other shakers, just for there to still be lumps. It's difficult to enjoy how great the other aspects of the product are when tue main function is so lacking. I'm yet to try it with a ball to see if it improves.

i have been using this product recently and my bollocks have gone massive my husband Andy thinks they are bigger than his!!!!

This product saves so much hassle. I didn’t think it would work without any mesh grids, however the design of the bottle makes it so easy for a refreshing protein shake within seconds

Pretty good shake, just shake to make! I put a little ball in just to make it extra smooth, and only use 2 scoops rather than 3 as that is simply too much powder!
