Great shaker. Well made and sturdy. I would like the measurements fo the liquid to be more visible.
On my second tub, absolutely love the flavour and half a stone down 😘😉
You can literally get next day delivery very fast and efficient
I'm addicted to this chocolate fudge replaces my sweet cravings. Losing weight too which is a bonus and noticeable in my clothes. Highly recommend this shake gorgeous with Greek yogurt and ice .
Mixes really well but you do need to push the top down hard til it clicks so it doesn't leak the markings for measurements need to be more clear tho
Shaker is an added bonus, mixes very well. Having the raspberry and white chocolate which is lovely, made with water but still really creamy
I am absolutely loving my journey with Protein slim, I can see the results in just 3 weeks of having a shake for breakfast and lunch, it keeps me full and the flavours are amazing ♥️
Loving the shakes! They are thick and creamy using just water! Looking forward to seeing some results.
Aweosme product! The shaker bottle is really easy to clean and works well. My only feedback would be that you need 250ml of water for a shake but the measurements up the side go in either 100mls OR OZs
Love the strawberry. Would be nice to get different colour shakers
The shake is so easy to make no need for an electric blender
Love the pink shaker, so handy and mixes well 😃😃
Love the shakes , I have blueberry, white chocolate & raspberry and mango and love them all. The shakers are perfect size for work and mix the powder and water well
OMG love this protein, l have the raspberry and white chocolate and its the best protein l have ever tasted, l mix with water and its honestly a treat and like a proper milkshake! Love it!!
I am loosing roughly 1 lb a day since using shakes twice a day, I use a calorie deficit app called my fitness pal to track my calorie intake. These Shakes taste great my favourite is white chocolate & raspberry, I love cappuccino iced coffee for breakfast. These Shakes are the best diet shakes, They are the only protein Shake that does not trigger my IBS, no bad stomach or stinky wind, Hurry up & get the shop restocked for me to order more. A very happy customer
These shakes are amazing. I work from 12pm to 9pm so dont really get to eat properly and these are a godsend. I have 2 a day and they stop me craving snacks and sweets. I love them, the flavours are great, I haven't really got a favourite as I love all the one's i have brought at the moment 😍 I'm waiting to try the vanilla but it's out of stock at the moment.
Love the shakes I have 4 flavours so far and you get a shaker free just perfect
Lovely shakes
Love the shakes very filling flavours are amazing, tried 6 so far what one to try next 🙂 lost a stone and a half so far so all great recommended highly
The chocolate orange shake is amazing it is lovely and smooth will be buying more saves having to buy chocolate and the shakers you get with them are really good
Lovely shakes nice and easy ❤️ 2 weeks 8lb down
Great shaker proper mixes up the shake
Brilliant little shaker. Doesn’t leave any lumps not mixed. Thick shake after wards
Nice shaker made well and is easy to use
I do add more water I have 320 ml of water and the three scoops. I have this as my breakfast meal and it certainly keeps me going til about 12 noon. Banana is amazing absolutely love it Strawberry is sometimes a little hard to drink for some reason don’t know why so thinking of trying another flavour just not sure what yet x
Would highly recommend as since starting Protein slim drink I am less bloated and have lost 9lbs in one month. Love the taste and it does suppress my appetite as I am not wanting to snack between shakes.
Delicious shakes that mix to perfection
Loved the taste, love that you can take with water, absolutely delicious with ice
I am thee fussiest person when it comes to flavours of shakes. The chocolate shake is probably the best tasting shake I have ever had, it's not sickly. I mix mine with cold water and crushed ice. I look forward to having it every morning! Even more than my first cup of tea.
Heard a few friends say their shaker isn't good,little,tip,make sure you push down the top bit hard and your good to shake it like you mean it 😉
Love love love! I mix with water because I have an unliking to milk and it’s unreal, thick and creamy!
Tried pecan latte , cappachino ice , raspberry and white chocolate, pineapple and coconut ,patiently waiting on banana arriving love them all so far , use as a quick breakfast on way to work and quick snack after work , stops me eating rubbish ,
I love the free shakers especially the black one
Pineapple and coconut is deliciously full of flavour. Its creamy and easy to drink as a replacement meal. 1st couple of days are tough as your body gets use to over coming the hunger pains. But honestly once you hurdle through that, 2 shakes and a main meal a day you really will start to see the results. 4lbs off in the 1st 5 days.
Love this shake & fills you up. I got raspberry & white chocolate and it's lovely but can't wait to try the chocolate 😋
I blend extra raspberries in my shake for a bit extra its delicious 😋
Totally love the shaker it's easy to use and makes the shake so smooth
Amazing taste! Keeps me full ! Was really surprised, other shakes I’ve tried just didn’t hit the spot. Made a smoothie with it too with 0% fat Greek yogurt extra pineapple and raspberries and water. Absolutely delish !!!!
Love the product
