    There's a reason it's nearly half off

    Cons: - The battery dies extremely quickly and either the claim "is designed to blend 15 smoothies on a single charge" is a straight up lie or I just happened to get one with a bad battery because there is no way on earth someone is getting over 10 smoothies on one charge - It does not consistently stay blending and I often have to shake the blender to actually facilitate the contents being blended - It often goes off while blending fairly soon without an adequate amount of time being blended - It's not entirely clear what the indicator lights are trying to say and the instruction manual was not very helpful at all - It often does not continue to blend when I turn it on and hit start and when that happens I have to just let it sit for a minute then try again... over and over until it works - "Leakproof Auto-Pop Lid" isn't entirely leak proof as sometimes contents leak where the lid hand is attached - Although it is very portable, it doesn't fit into my car's cupholder, which I thought it would have - "Unique Angled Blade Powers through ice and tough ingredients with ease," yet I typically have to pour very hot water in there otherwise the blade does not power through with ease - It's not sold through Bestbuy so I can't return this now and even though I can't, I am still planning to try the Ninja Blast Max Portable Blender because this Oster product is honestly pretty disappointing Pros: - Affordable - Seems decently well made - It is very portable (minus not fitting in the cup holder) I would NOT recommend this and like I said in the cons, not only will I be trying the Ninja blender instead, I am also getting my gf one of those as well instead of this. I am submitting a request to the seller to return this product due to many of the claims not being true.

    I’m impressed with the power and battery life of this thing. The blades reverse to avoid jamming which is also nice.

    VERY HAPPY with this purchase! I have had and have multiple blenders for smoothies, cooking, etc. as costly as $500 units. This little beast has become the go to blender for smoothies and has worked like a charm with frozen fruit, ice, granola, etc. My son then takes it to go on his way to school or practice so it is super convenient. Very dependable brand OSTER so you can't go wrong. Highly recommended as a secondary small portable blender for small cooking options and personal smoothies, etc. A+

    This is my new go-to blender! It quickly and quietly pulverizes ice cubes and frozen fruit into the perfect smoothie. It really is portable with many smoothies per battery charge. This is great for travel, I can still get in my protein shakes and smoothies when not at home. Also ideal for mornings on the way to school, work, or the gym. Clean up is super fast and easy. You will love this!

    Unfortunately it started making a grinding noise so I did some troubleshooting based on their own forums and instruction manual. I was trying to reset the battery but what I removed the screws from the bottom a bunch of parts of the magnet that surrounds the inside of the electric motor came out crumbled and it no longer works. The motor literally broke inside with fragments of magnet all over the inside of the device so now I have to deal with a warranty replacement and probably paying money out of pocket to ship it back to them which isn't fair to me as the consumer so I would not recommend it.

    It ran great without any leaks for 2 months. Then regardless of how I set the seal, the blender started leaking liquid. I even tried blending with lesser amount of liquid and fruits, it still leaks. It’s a shame, it is powerful machine.

    Enjoy using this product. Specifically for on the go. The power is great. Only downside is that the inner washer moves around, which causes the unit to not operate. Have to realign quick a bit. Other then that it is great.

    This was a gift but the giftee (a person who doesn't like every gift received) keeps commenting about how often it is used and how well it works. That you just turn it over, after blending, unscrew the blending attachment, add a cup bottom, and drink--makes cleanup so much easier.

    I purchased this product and it worked well at first, it's a little clunky as the arrows have to line up but worked well for abt two weeks then broke. Arrows aligned, everything correct, charges but would not spin. I emailed customer service through best buy February 22nd, I sent pictures and videos to a separate email they requested as well and have followed up just about every week. Below is the same message I have been getting for weeks with no resolution. It's April 20th, 2 months since my product boke and no resolution. DO NOT BUY! Oster message Hello Jason, We sincerely apologize for the inconvenience this has caused. you. Please be informed that we already sent your message to our tream regarding the replacement. We will contact you as soon as we receive an update. We appreciate your patience and understanding as we work to resolve this matter.

      Hello, thank you for sharing your experience, and we sincerely apologize for the frustration and delay you’ve encountered with your Oster GoMax 20oz Portable Blender.

      We’re very sorry to hear that the unit stopped operating after only a couple of weeks of use, especially after you followed the correct alignment steps, confirmed charging, and provided the requested photos and videos. That’s not the experience we want for our customers, and we understand how disappointing it is to still be waiting for a resolution after multiple follow-ups.

      We also regret the lack of timely updates in your case. Extended delays without clear communication are not acceptable, and we recognize how that has added to your frustration. Your feedback has been shared with our support team so we can improve responsiveness and follow-through in cases like yours.

      At this point, we want to make this right. We recommend reaching out again to BestBuy and referencing your original case number along with your Best Buy support thread so they can escalate it appropriately. You may also contact Oster customer service directly to request escalation to a supervisor review for faster resolution.

      For assistance, please do not hesitate to get in touch with us directly. You can do so via the 'Contact Us' form on our official website. We’re available Mon.-Fri. 9 am - 5 pm Eastern Time.
