It's nice to have a quick bite/shake/drink to keep you full for a few hours. I guess it suits a workout schedule, easy to count kcals, protein,... Not the biggest fan of the apple/cinnamon shake. Wanted to try something new, but still prefer the banana flavor. I love the Plenny Bar! It's chewy, tasty and really filling. The Plenny drink is good, better than the shake in texture, less grainy and smooth. Still very thick, like porridge. All in all I would rate the shakes 3/5, the bars 5/5 and the drinks 4/5. Last thing I'd like to add: It's not really a meal replacement - the 400kcals per dose keep you going for about 2-3 hours, you'll be very hungry if you stick to only 3 per day, you'll need an extra meal. And then it may become a bit too expensive.
