Smartshake Reforce Stainless Steel Protein Shaker 900 ml - Leakproof

Our review of the Smartshake Reforce stainless steel shaker finds it best suited to gym-goers and anyone who mixes protein or supplements on the go; its single biggest selling point is the combination of durable food-grade stainless steel and a genuinely leak-proof screw-on lid that eliminates rattling and spills. The 900 ml capacity handles large servings, while the matte powder coat and soft silicone base add grip and protection. This review focuses on real-world use, noting the solid build, the silent mixer net, and practical markings for measuring ingredients.

Key Features

• Durable construction: Food-grade stainless steel 304 offers longevity and a hygienic surface that resists dents and odors.
• Large capacity: The 900 ml (30 oz) volume is useful for longer workouts or for people who prefer larger shakes without constant refills.
• Leak-proof lid: A screw-on, solid lid design prevents spills and removes the loose-part rattle common in other shakers.
• Silent mixing: The signature mixer net snaps into place to create smooth, lump-free shakes without metal balls or extra noise.
• Practical details: An engraved measurement scale inside the bottle and a wide opening make measuring and handwashing straightforward.
• Safe materials: BPA- and DEHP-free components meet US/EU food safety standards for everyday use.

Who It's For

The Reforce stainless steel shaker is ideal for regular gym users, athletes, and commuters who need a sturdy, leakproof bottle that can withstand daily knocks and travel. Its 900 ml capacity suits those who mix larger protein portions, meal replacement shakes, or rehydration drinks for extended sessions.

It is less suitable for people who require temperature retention since this is a single-wall, non-insulated bottle and should not be used with hot liquids. Also, those who only need small 12-16 oz servings might prefer a more compact shaker.
