Nice small blender
on December 9, 2025
Posted by: caseyb93_41
[This review was collected as part of a promotion.] I love this little blender. It fits in my lunchbox and is powerful enough to chop the most frozen of fruit. I also have mixed my protein shakes in it successfully. It is easy to clean and charge. The only thing I don’t like is having to keep up with the secondary lid if I don’t want to take the blender part with me.

[This review was collected as part of a promotion.] The Oster GoMax Portable Blender is super convenient, blends surprisingly well for its size, and is perfect for quick smoothies on the go, just don’t expect it to crush big chunks of ice like a full-size blender.

Smoother and creamier

[This review was collected as part of a promotion.] This GoMax portable blender is awesome! I use it for my quick smoothie drinks and it leaves them smoother and creamier. I can use it plenty of times with one battery charge. It’s also super easy to clean which is a big plus.

Great device, just heavy!

[This review was collected as part of a promotion.] This portable blender works great for morning smoothies! The blender is easy to put together. It's also very easy to take apart and clean, using a twist off method to get most pieces apart. The bottle is pretty heavy, so it's not the easiest to carry around.

Well… this was a flop
on December 13, 2025
Posted by: sierraforeman9110_8161
[This review was collected as part of a promotion.] It does not blend ice or even cottage cheese up very well.. it just seems to get stuck at the bottom and the blender part keeps spinning away, making no progess… but, it’s good for mixing protein water or protein shakes- and honestly, that’s about the extent of its limitations. It’s easy to clean and assemble.. but as far as safe? The lid opens while it’s blending, so, that’s a concern. I really wanted to love this product, but they have many improvements to make before I’d spend my own money or recommend this to anyone.
Response from influenster.comBy Customer Care, December 19, 2025
Hello, thank you for taking the time to share such detailed feedback. We’re really sorry to hear that the GoMax Portable Blender didn’t meet your expectations, especially since you were hoping to love it.
We want to acknowledge your experience with blending ice and thicker ingredients like cottage cheese. The GoMax is designed primarily for lighter-duty blending, such as protein shakes, smoothies with soft fruits, and liquid-based mixes, so your observation that it performs best with protein water and shakes is accurate. For thicker or frozen ingredients, results can vary depending on ingredient size, liquid ratio, and blend technique. Using smaller ice cubes, adding liquid first, and pulsing while gently shaking the blender can help, but we understand this may still fall short of what some users expect from a blender.
We’re glad to hear that you found it easy to clean and assemble. Portability and convenience were key goals in its design. That said, your comment about safety is especially important to us. The GoMax is designed with a safety interlock that should prevent operation if the lid is not properly secured. If the lid is opening or loosening during blending, that is not expected behavior and could indicate a defect or an issue with assembly.
Your feedback about needed improvements is valuable and is shared with our product development team as we continue working to improve performance, blending power, and overall user experience.
If you need further assistance, please reach out to us via the Contact Us form on our official Oster website https://www.oster.com/support/contact-us. We’re available Monday to Friday, from 9 am to 5 pm Eastern Time. We look forward to assisting you!
Thank you, and please stay safe!

Great on the go blender, minimal noise
on December 13, 2025
Posted by: anhelinas1_7097
[This review was collected as part of a promotion.] The Oster GoMax Portable Blender has been a great upgrade from a traditional blender. I love the convenience. You can load up your ingredients in the morning, toss it in your bag, and when you’re ready for a smoothie, you can blend it on the spot. It’s super quiet, so even blending at the office won’t disturb your coworkers.

Great portable blender
on December 14, 2025
Posted by: jocelynl79_7065
[This review was collected as part of a promotion.] Great portable blender for smoothies, easy to use and makes mornings easier. Only drawback is you can’t put too much ice in your smoothie as it ends up leaving chunks of ice, it’s a strong blender but not the strongest since it is a portable version, not full size, so it’s expected.
