"I would definitely recommend this shaker if you're looking for something strong, durable, and reliable. The quality is excellent, and it does exactly what you need it to. My only suggestion would be for ON to consider lowering the price a little, making it more affordable for everyone. At a lower price point, it would be an easy purchase that people could make without a second thought."
"The Optimum Nutrition Opti-Lock Shaker is durable, leak-proof, and mixes protein shakes really well without clumps. It’s easy to clean, lightweight, and perfect for gym or daily use. Highly recommended!"
"Uitstekende fles! De sluiting is geweldig, de shaker werkt heel goed, de antislip onderkant geeft veel stabiliteit en ook het sluitsysteem met vergrendeling is uitstekend. Een zeer goed doordacht product van topkwaliteit!"
"Wirklich die neue Generation von Shakern. Durch den Verschlussmodus bleibt es auch nach mehreren Spülgängen noch superdicht!"
"Its perfect can't fault it"
