I love this!
[This review was collected as part of a promotion.] I have used this blender for soooooo many things! Sauces, salsa, and smoothies! It has some great power and it’s small! I love it because I’m not having to use my big blender for much anymore. The battery life is great! I haven’t charged it since I received it! Easy to turn on and off!

Great portable blender
[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.

Great on the go blender, minimal noise
[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.

Well… this was a flop
[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.

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! Oster Consumer Care

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.

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.

Nice small blender
[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.

Great concept, not a perfect execution
[This review was collected as part of a promotion.] *I received this product for free in exchange for my honest review* I love the concept of this blender. However, I found that you can’t fill the blender up to the recommended maximum and have it blend properly. If you fill it up about 75% of the way, then it works just fine. I love the concept of a portable blender but found it difficult to remove the cup from the bladed portion due to the condensation from the cold liquid.

Portable
[This review was collected as part of a promotion.] While it is portable it is warned not to take it anywhere I worked good grinding sugar so I imagine it’ll be good for fresh fruits don’t know about frozen fruits. It isn’t very practical when it comes to washing it or taking the top off

Multi greatness
[This review was collected as part of a promotion.] Great product. I test two different types of things to blend. I blended a powder down really nice and fine. I also made a smoothie and they blended quickly. I love how it starts and stops then adjust and starts again. Super easy to clean and take on the go.

Portable, light-weight, functional!
[This review was collected as part of a promotion.] I like that the blender is lightweight and it is portable, so I could just put in some frozen berries and milk and then start the blender while I’m starting the car, which is great because I am always running late :) I also like that it comes with a handle so I wouldn’t have to worry about the bottle slipping out of my hand because I have really small hands.

Multi use in the kitchen!
[This review was collected as part of a promotion.] Such an awesome kitchen tool to have!! I know the photos are marketed for smoothies and such but I’d actually like to use this for sauces, salsas, or thin batters. The size is super compact, easy to take apart and clean, and looks aesthetically nice.

powerful and convenient!
[This review was collected as part of a promotion.] blends frozen fruit and ice thoroughly, great size and top for drinking. I do wish the battery disconnected instead of removing the whole bottom to put the flat bottom on. that would also be helpful for cleaning the blades. they’re hard to clean when you can’t remove them from the battery.

Impressive power for its size
[This review was collected as part of a promotion.] I recently got a chance to try out the Oster GoMAX Portable Blender and it’s been a surprisingly solid companion for my kitchen and on-the-go smoothie needs. The first thing that impressed me was how powerful the motor feels. It easily handles blending when I toss in frozen berries, spinach, or even small ice cubes. I appreciate how quiet it is: I’ve used it early in the morning before the family wakes and it doesn’t draw unwanted attention. The USB-C charging is a big win too. It's convenient for charging in my kitchen, in the car or in hotel rooms without plugging into a full outlet. That said, it’s not without its trade-offs. While the motor is impressive for a portable unit, it still doesn’t compare to full-sized plug-in countertop blenders in terms of raw power or capacity. If I try to blend large chunks of frozen fruit or tougher ingredients like large raw vegetables, it struggles a bit more than my standard blender. The jar size is modest, so for bigger family batches I still reach for the larger unit. In other words: it’s a fantastic portable/secondary blender, but don’t expect it to fully replace your heavy-duty blender whenever you’re doing large-volume or ultra-tough blending tasks.

Powerful and portable.
[This review was collected as part of a promotion.] I was sent black instead of blue haze, so my review will be based on the black color. The motor on this portable blender is super great. It blends in both directions extremely efficiently, and if something gets clogged it redirects it for a moment or turns off to save the motor. The portability is absolutely amazing, hands down such a great feature and works quietly. When you hold your drink with the base it's a bit heavy, but it isn't too terrible. Luckily, it comes with an extra lid so you can detach it from the blades completely and leave the base behind while you enjoy your smoothie. My one concern is durning washing. I have been using my thumb to plug up the USB when rinsing, but I worry about water easily getting into the battery since the design of the blade is attached directly to the charging base and doesn't remove. I worry this blender might not have a ton of longevity because of that. Washing concerns aside, our family is busy, and there have been several times I've loaded my morning smoothie into this and made it while driving to school, which has been a life saver. Overall it's a great powerful blender and I love having it.
