It is a little hard to blend anything that is frozen like a banana.Purchased 2 blenders, one for myself and one for a friend, to blend protein powder mixes and maybe some fruit for smoothies. The motor isn't as powerful as I had hoped, but it still does the job well when it comes to blending everything up. I also love the built in "strainer" as well. The cup is 13 ounces so it holds just the right amount of mixture that I need each time. Love the colors as well. If you're looking for something economical, but still does the job, this one will work. It has for me.IM UPDATING MY REVIEW! SO THE FIRST ONE I GOT ONLY WORKED FOR A COUPLE DAYS, I LEFT A REVIEW AND THE OWNER EMAILED ME AND STATED THEY WOULD SEND ME A NEWER VERSION AND STRONGER! SO I AGREED AND IM IN LOVE AND COULDN'T BE HAPPIER! ITS STRONG AND DOES ITS JOB ON THE GO! IM ALWAYS IN A HURRY IN THE MORNING FOR WORK AND THIS HAS HELPED ME SO MUCH! I NEVER MISS HAVING MY GREENS IN THE AM BECAUSE OF THIS MACHINE! I WOULD 100% RECOMMEND GETTING!HAPPY CUSTOMER :)This little rechargeable blender is not intended to replace a full-size blender, nor will it be able to do everything that a full-size blender can do. With that being said, I have to say - after my first week of using this Amazing little blender - that I don't know how I've been getting along all my life without it! I've been using it two to three times a day and I just can't get enough of it! This is the Coolest Gadget you'll ever buy, and it's the exact same portable rechargeable blender that I've seen selling elsewhere for nearly twice the price that I paid for it right here on Amazon. It runs for DAYS at a time on a charge and it's so easy to clean after each use. If you buy any of the popular powdered health drinks like Super Beets you know how hard you've got to stir it into a glass of water to get it to mix in. And no matter how hard you stir it - it still doesn't fully mix in as you find out after you drink it down and there are undissolved clumps of it on the bottom of the glass. But with this handily little blender you'll give your hand and wrist a well-deserved brake and eliminate the endless stirring and instead, just push the button and in just a few seconds the powerful motor and the very effective dual blending blades go to work to quickly blend every last grain of the powder into solution with ZERO sediment at the bottom. I love how quickly I can whip up a delicious fat-free chocolate thick shake with skim milk, my favorite rich chocolate protein powder and ice - and I use crushed ice from my fridge door dispenser, which is much easier for this little blender to blend into a delicious thick shake. If the blades jam when you press the button - No Problem - because you can quickly do something with this featherweight little cordless blender that you simply can't do with a full-size blender - you can pick it up and turn it upside down to instantly free the blades - and even shake it a bit as needed to assist the blades in grinding up large pieces of ice. Trust me when I tell you that you'll fall in love with it, and find so many uses for this very cool, rugged and well-made little blender! Needless to say - I Highly Recommend it!Portable Blender for Shakes and Smoothies, OBERLY Personal Blender for Protein with USB Rechargeable, 6-Point Stainless Steel Blades, 13oLove everything about it. The price point can't be matched for the power and portability of the product. Would definitely recommend.It’s okay. You get about 10-13 oz of usable space if you don’t put too much ice or fruit in it. I used small pieces of frozen fruit and it shut off three times on average and I would have to shake it and restart. It’s a good idea, but no where near a replacement for a magic bullet. It’s lack of power is not made up for in portability and minimizes it’s convenience factor.I love the fact that it is portable and doesn't need to be connected the whole time! There is only one button and It has a built-in timer that should be adequate for most of the blending works. It comes with 50 classic smoothie recipes, I tried three of them and all taste great! Also love the mini ice cube mold tray, very cute and effective. I found it easy to clean with a sprinkler, then I just tilt it upside down to dry off. One suggestion I would make is to make the start button less sensitive (especially in the cleaning process, may accidentally press on while cleaning the blades. Maybe make its position less obvious for fingers, or add a safety cap ) Overall it does what it described, the battery life is also amazing, will recommand!This is nice addition to my beverage to go for work. I just put everything at night and get it ready for next day. Its portable but power is pretty good to make my smoothies. It works wireless so i can make it anywhere. Size is good for one and i carry a spare cup just in case if i have company. One week it and i feel healhyFirst off, the product came in a damaged clearly already opened box. I was skeptical to try it but figured why not I already have it. I cannot believe how tiny it is and also extremely disappointed in the blending.... my battery only lasts on a full charge for one blend and it barely even gets the job done. Would not recommend wasting your money on this product simply because it literally is a waste of money. Save your time and busy yourself a Blendjet or something that is worth your investment.It looks nice and have a good build quality. Easy to use and wash. Can be carried with you anywhere. I thought the delivery might be a problem but surprisingly it came before expected date. Thanks
