Süß aber ok

Review by L. on Jul 15, 2020
Cookies and Cream ist mir persönlich zu süß, aber wer darauf steht wird zufrieden sein! Löslichkeit ist in Milch wie in Wasser sehr gut.

Review by Anouk on May 22, 2020
Ich habe Vanille genommen, da es kein Schoko mehr gab und es schmeckt extrem eklig. Ich habe bei vielen gesehen, dass die dadurch zugenommen haben, aber wegen dem Geschmack kann ich das einfach nicht trinken. Ich habe es jetzt schon ein paar mal versucht, aber der Geschmack ist einfach nur schlimm. Ich weiß nicht, ob es nur Vanille ist aber ich kann euch auf jeden Fall nur davon abraten Vanille zu kaufen. Schade, da ich gehofft hatte dass das Produkt funktionieren würde.

Meer dan tevreden

Review by Koen on Apr 24, 2020
Nog nooit eerder gebruikt, ben meer dan tevreden. Bananen smaak is werkelijk net een Milkshake van de M*D*****s. Tip: Doe het met wat melk/ water èn ijsklontjes in de blender en je hebt een milkshake! Top product.

Review by Bob on Mar 22, 2020
Als nog niet weet hoe de verschillende smaken zijn raad ik aan om de banaan te nemen (Als je banaan lekker vind) deze is lekker zoet en drink je zo weg.

Review by Wilbert on Feb 25, 2020
Smaak: Banaan is een goede aanrader! Het lijkt erop alsof die ook minder klont dan de smaken chocola / aardbei. Veruit de lekkerste!
