Got this deal last week thanks to Anurag bhai. (around 3kg protein for 460. 1.5kg was maiva pro and 1.5kg was Nourish you (chocolate) will review later.)

I have tasted Yoga bar whey and plant unflavoured, Amul whey chocolate, Fitspire whey (pista). so my review will be based on that. 

Packaging: 4/5

I have already used up 2 package of 250g (my whole family drinks it. so it gets used up faster)

Unlike other brands it didn't become loose. Still works fine after usage of week. 

Mixability: 3.5/5 

It gets mixed fine with moderate foam and it gets away after stirring with spoon. Usually I shake 15-30 seconds but there are some small lumps sometimes. And I can feel I'm drinking powder. This issue is both in drinking with water and milk. 

I haven't felt any bloating till now. I just feel little full for a hour and sometimes sleepy when I drink it after workout. 

Taste: 

As I got assorted one too I tasted all flavours. By far mango is best flavour. Mango (3.5/5)>vanila(3/5)>coffee(3/5)>chocolate(2.5/5)>unflavoured(meh, don't recommend) . 

Even though I like chocolates generally, this chocolate flavour isn't that good. Still, it's bearable as I usually use yoga bar unflavoured plant protein. 

I would suggest to mix in milk and they will taste better. If you are cutting mix water and low fat milk. Even my mom who don't like protein powder, didn't notice taste of mango flavour (with milk). Still they use natural identical flavours so don't get high hopes. 

For sweetners they use dates and monk fruit so it's not much sweet. chocolate and coffee flavour is bitter too. I liked coffee one. 

Final review: 

If you get it in low price it's a good deal. Otherwise don't buy it. As there isn't any much report regarding this. Reviews are mostly mixed as much I have researched. If you can afford it's good for vegan option.
