X: 16,000RPM USB Rechargeable High Power Electric Protein Mixer - Portable Electric Vortex Mixer and Shaker Bottle with Supplement Storage and 600ML Capacity Stainless Steal

Loving this mixer bottle. Son is using it to mix his post-workout protein. Nice strong motor. Also is convenient having the storage compartment. Had some issues initially, but ShredTech was GREAT AND QUICK in resolving them. Even though we has those issues, I am still giving them a 5 star rating. (I have not been compensated in any form for this review)

Worked great for agonist 2 weeks them batter died our so I thought so I recharged it then went to go use it again would only run for 15 to 25 seconds then turn off. Kept pressing button to turn on and would not turn on. So I removed the base to try and see what was wrong and it works fine when the cup portion is not attached but as soon as I attach it won't run. Was very happy at first but now just let down does not seem to be well made. Try a different company!!!!

It mixes well. It will run for a couple minutes and then shut off. Wait a couple minutes and it turns back on and repeats the cycle. The speed of the mixing does not change so I do not think it's a battery issue.

works good but loses charge somewhat quickly easy to clean and good storage.

I had to return it because the batteries did not last.

This portable blender is awesome, it does all that I asked for. Only downside is that it doesn't crush ice. Other than that, it's great.

Bottle stop working after one day of use mixed ok on the first day but after first day only mixes when plugged in if I don’t have it plugged in it won’t mix anything I wouldn’t buy this again

I have bought three of these and finally decided to switch to ‘pop-babies’. Everyone else seems to have had speed or battery problems but mine would work great for a little over a week without a charge and no problems?? All three Blender bottles I purchased mixed everything I needed to without any problems. You’re probably wondering why three stars then? It’s because the quality of the plastic is crap. The first one I purchased I didn’t always wash right away so after so many twists off and on to clean it, the plastic stops broke so I couldn’t attach it to the blender motor. I decided to take better care of the next two by washing them per instructions (right away and with the blender function instead of cleaning tools). Both of the second two I bought broke within 3-4 months. One got kicked over accidentally at the gym by someone who didn’t see it and the plastic near the lid cracked so everytime I went to drink it would leak. The second one was about brand spanking new that I dropped myself on thin carpet because my dog yanked on her the leash causing me to drop it. The bottom base cracked and leaked everything out onto the motor and the floor.Overall i would love the shredtech blender bottles if they upgraded their plastic at least. The motors worked great for me but having to be that careful is too tedious. You basically have to baby the thing and having to purchase one every 3-4 months just isn’t worth it. I am generally pretty careful with all my things but accidents happen and these bottles are certainly not accident proof. Not even minor ones. Hope this helps
