Not too sweet - Not too thick - Nice low calories.
Love, love these Slate protein drinks. Not too sweet or too heavy. Just right, and I hve them either if I am rushing and no time for breakfast, or for lunch with some Scandinavian crispbread and a slice of cheese, or just in place of dessert. Will continue to buy them.

Good Taste & Quality! Just Shake Well! Vanilla Flavor
Animal protein is the best protein!! Nothing like good old fashion milk! Especially if you want to avoid high led contamination which most plant proteins have because plants come from soil. The taste is great compared to others. Limited ingredients, lactose free. Many are complaining about the globs at the bottom. You must shake first. However it it’s really cold from the fridge then some can get stuck I noticed. If at home you can just pour into a blender and mix. Or if traveling use a straw to stir the bottom. Only complaint I have is the price.

Horrible fake taste
Disgusting!! I am used to other mainstream protein drinks (premier and fairlife) and this one was by far the worst! Couldn’t even finish the bottle. Like sucking on chemically enhanced vanilla sucralose. So fake tasting, and the consistency is gross - kind of thick and settles at the bottom despite shaking well. Just awful. I don’t even write reviews normally but I couldn’t let this slide. Since I didn’t want to drink it straight I tried putting a little in my coffee and even that was gross and I made a new cup. If l were to define “repulsive” this would be what I’d chose.

Every flavor CHUNKY yyyyuck
Tried every flavor — no matter what you do or how hard you shake it, it’s chunky and the protein never fully incorporates. Originally I loved these but then realized there was lots of protein left at the bottom every time… no matter how hard or many times I shake it, it’s chunky. So, either don’t get the full serving of protein or get a chunky serving ☹️

Dont buy this.
Gross had chunks of what I can only compare to mucus at the bottom. More than one can had this. When I tried to do a return, I was told to bring it to the store. Uh, no. I had it delivered. Just refund my money. This is a disgusting product and no one should ever drink it. Both the vanilla and the chocolate had the mucus snot chunks.

Vanilla across the four pack stays consistently tasty, rich, and smooth. Great value if you already love the flavor and want a steady supply.

Not too sweet. Not too chalky. However despite shaking the can before opening both times, when you get to the bottom of the can there is some chunkiness/ stuff stuck to the bottom of the can.

A Good Protein Shake
I am very particular about protein shakes. That being said, I do really like this one. It tastes great and is more like a milkshake. Bonus: it is lactose-free. There is a slightly weird taste from the stevia, but it’s not bad at all. Overall, it's a delicious protein shake with high protein and a good vanilla taste. Just wish it were a little cheaper. Four cans for $10 seems a little pricey to me.

Gave these a try; the taste was good but when I got to the bottom of the can there were chunks of something so ended up tossing the rest. I did try 2 cans to make sure it wasn't just one of the cans. Will never buy this brand again!

Huge Protein Boost!
I love that this protein shake is made with ultra-filtered milk. Tastes exactly like vanilla without being overly sweet. Excellent value as well.
