SmartshakeSlim Protein Shaker Bottle With Storage 400ml to 500ml Leakproof BPA Free Small Protein Shake Bottles Smart Shaker Cup for Women + Men (Neon Blue)

Perfect protein shaker. Nice size that fits perfectly in the bottle holder of my bag. The compartment on the bottom is great for carrying protein powder in, so there is no need to premix before heading to the gym. The filter at the top of the cup acts as a blender as well as a filter for lumps and the clip on the side is handy for attaching to your bag if you are lacking in room! I haven't had any problems with mixing my protein powder to smooth shake compared to other protein shakers I have used previously with the metal sprung balls in. Overall a nice product that I would recommend!

UPDATE: i've now had this shaker for about 4 months and was using it regularly BUT its started leaking through a hole in plastic seam in the bottom of the cup which is not supposed to be there. Disappointing as it's now uselessGreat cup, simple and easy to use - never have clumps in my protein and it just goes in the dishwasher when I've used it which is a bonus. I've also washed it by hand which isn't an issue at all, I just prefer it being dishwashed. I've removed the bottom compartment to make it a bit smaller and more convenient for me as I'm only using it at home but I imagine it's very useful if I were to want a protein shake after going to the gym once they open again! Overall great cup would recommend

Good small shaker. Can only fit 1 medium size scoop in the bottom storage part. Has leaked when fell over in my bag

Really great cup! It’s leakproof and easy to clean and use, I bought three of them in different colours!! They’re great! Very handy that they have the extra compartment on the bottom so you can bring shake power with you or even a snack, super handy! Even comes with a clip incase you don’t want to carry it in your hands

Very good bottle, i bought two, the top is very tight and it doesnt drip at all when shaking proteins

I have four of these shakers and they are the perfect size for carrying around or using in a car cup holder.

The bottle leaks every time I top it up with water. It's a pity as the bottle is slim, compact and good value for money, but does not do the job unfortunately.

Great shaker, mesh compartment guarantees a frothy shake after your 20 second arm workout! The extra compartment at the bottom is a great idea, allows you to take your shake to work without having to pre-make and the shake becoming gloopy later on
