Smartshake Slim Protein Shaker Bottle With Storage 400ml to 500ml Leakproof BPA Free Small Protein Shake Bottles Smart Shaker Cup for Women + Men, Gunsmoke Black (Gunsmoke Black (2%))

For its purpose it's perfect. The cup at the bottom screws on and doesn't leak like some that clip on. The lid is secure and needs a good push down so it won't leak. Hard to see measurements on the side but they are there! Good for weight watcher shakes.

I like the fitting inside which helps mix your shake without clumping. Easy to clean as it comes apart.Handy compartment means you can setup a shake to have later.

First impressions- Alot smaller than expected!-Very slim and short, more akin to travel flasks than your usual protein shaker (See picture with the massive 650ml USN shaker and standard blender bottle for scale. This gives it a slightly feminine air.-If this doesn't bother you then the ergonomics, handling and all round convenience are unparalleled!-Shakes flawlessly (Almost too well, froths the liquid with too much shaking but this settles down if left for 30 seconds) and very easy to clean afterwards (No tight spots for stuff to get stuck in)-Good quality thick plastic for the lid and the body, however the powder compartment is made of a more flimsy plastic (seen bending in the attached picture) which is the reason for the 1 star off.-Indicated as fridge, freezer, dishwasher and microwave safe and can take liquids up to 120 degrees Celsius and is DEHP & BPA free (Though id never microwave and freeze plastic this is quite reassuring and indicates quality)-Have been using for 2 weeks and theres been no leakage whatsoever with a secure click to close lid (Even when dumped mostly upside down in a rucksack for hours)Overall very happy with this shaker and it feels great in hand (Other than the flimsy bottom)NB/-Powder compartment holds 30g powder or 45g if compressed (ie. 1 scoop of protein or 1.5 at a stretch) so if you take double scoops this inst for you.-Very hard to actually see the level of liquid and the corresponding volume markers; so if you want to be precise with measuring volumes with this, youll really have to squint (at least with the black colour)

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!

Best shaker I've had. Slightly smaller makes it easier to pack inside bag etc. Had mine ages and lasts unlike others which break.

The best on the market regarding the size. Small and compact. Looks durable and mixes well.

Would advise to buy others, not worth the price for the poor quality

Nice bottle, I bought for my partner it was slightly smaller than expected (I just assumed it was the usual size I didn't check before buying) all in all good purchase but better for me he needs a bigger one.
