Protein Shaker Bottle, USB Rechargeable 600 mL Vortex Mixer, High-torque Tornado Shaker Cup, Portable Stirring Blender for Powdered Supplement Shakers. BPA Free, Guaranteed Leak-proof.

When I first got this product I used it for mixing up energy drinks, so more of a light powder compared to the protein shakes, but I figured this was heavier duty since it is listed as a protein shaker bottle. The mixing pieces worked really well and I used this product a lot.Fast forward a month or so and really, the product is just so-so. Sometimes the stirrer gets jammed from starting and I have to give it a little twist below the bottle to get it going again. When you use a thicker powder, it really struggles. The battery seems to last well, however. Also, there's a bit of a design flaw around the drinking spout. There's no easy way to drink what you've mixed up, it just ends up being awkward. Plus, with the way the spout is designed, you always get some remnants jammed in the corner between the spout and the upper rim of the lid, which is difficult to wash out by hand.In the end, it's decent at what it's designed to do but I don't feel like I got my money's worth. If you keep using it with light powders, you might be ok. But it might jam like it did for me, and become more trouble than it's worth. So....your mileage may vary.

I paid a little more for this one over a Chinese/Foreign model because I had one previously, and it broke within a year. It started leaking 7 months in, and the motor went nuts a month or so after that. I wanted something higher quality and am always fond of things made here in America. I got the bottle, and it looked very similar to the previous non American one I had before. It does work as it's intended, though sometimes the mixer won't stay on, and you have to keep the button pushed yourself. Sometimes it will keep going, other times you have to sit there and keep the button pushed. It's decent, and has a year warranty so I'm excited about that, because I know I'm at least covered for the year unlike my other one. I think the warranty and that it's made in America is worth the extra money over a cheaper foreign blender bottle. I hope the motor doesn't have the same fate as my last one!

Very mehIt works well for the most part mixing powders.My personal experience is the battery life is a joke. I will get maybe, maybe, a preworkout, bcaa, and protein after a workout on a full overnight charge. That is a strong maybe though. I literally never use mine unlpugged at this point, and I have had it for less than a month.The spout could be bigger, kinda odd with how it doesn't really flow well with thicker mixtures.I'd say better than your typical blender bottle or similar, but would not buy again.

Wow! This was the first time I had ever received an electronic product that actually came with a charge! I had purchased a competitor's bottle and decided to give this model a chance after I gave up with my last one. This blender blows it away...hands down. This mixer is deceivingly powerful. I like my shakes thick, and this bottle has no problems with that. The charge also lasts for many different shakes, much longer than my old bottle. The quality and style of this bottle is also top notch. I dare you to try and spill it!Without a doubt this is the best value electronic mixer on the market! Don't waste your time and money with other options.

The bottle is a solid container that I doubt will ever shatter.The stirring action seems strong enough for any mixture. Its not going to blend anything, but it can handle 3 scoops of protein easily.I give 3 stars because the thing won't turn off. I press the button and sometimes it turns off, only to turn back on a few seconds later. Or it just refuses to stop spinning period. Very annoying.

Wow, this blender works great. DO put the liquid (milk, water etc) first, then put the product in and mix. This will help the life of the motor and the mixing apparatus. It is very light (lighter than I expected) but made out of solid material that cleans well, too. VERY important to someone who uses shake bottles for protein a lot for working out. Make sure the motor is charged from time to time (you can plug the usb plug even into your computer as needed) and you will be good to go. Overall, a great experience so far.

This bottle was definitely worth the money! It has a powerful battery pack that charges in less that 5 minutes when completely dead. I mainly use it for flavored water but it could be used for lots more. I really like that the base can be removed from the battery pack for more thorough washing.

I highly recommend replacing your standard fitness shaker bottle for this higher end solution! There are virtually no clumps left at the bottom of your drink as found using conventional shaker bottles which leads to highly quality drinks and less waste. Clean up is a breeze as well now. With one drop of liquid detergent and water, you can hit the button and 20 seconds later, have a clean and sanitary bottle ready to go for your next workout. Do yourself a favor and toss your typical blender bottles for this upgrade, you won't regret it!
