VOLTRXProtein Shaker Bottle, Merger USB C Rechargeable Electric Protein Shake Mixer, Shaker Cups for Protein Shakes and Meal Replacement Shakes, BPA Free, 24oz

Great value, stays charged a long time and mixes very well! I have tried mixing other non protein powder items like very ripe bananas, ice cream and peanut butter. Though this is not a blender, with a little finesse you can break them down as the rest of your shake mixes.I say this to highlight the durability and power this mixer offers all while being leak proof and in a size that allows me to mix a double scoop serving.Overall works well and easy to clean!!!!

Forget everything you thought you knew about shaker bottles. The Helimix 2.0 is on another level — a beautifully engineered piece of gym gear that mixes with pure vortex energy. No blender balls, no blades, no extra parts to clean. Just an effortless, swirling tornado of perfection every time you shake.From my first use, I was amazed — my protein powder dissolved faster and smoother than it ever did with traditional shakers. Even thicker mixes like casein or meal replacements blend beautifully. The unique hexagonal design isn’t just for looks; it’s functional science that turns a few shakes into a creamy, lump-free drink.Build quality? Rock solid.The BPA-free plastic feels premium, durable, and it survives drops, rough gym bags, and dishwashers without a scratch. Plus, it doesn’t hold onto odors like cheap shakers do (finally!).Cleaning? Two words: Game changer. Just rinse and go — no more fishing blender balls out of the drain.If you take your shakes seriously and want the smoothest, most hassle-free experience, Helimix 2.0 is absolutely worth it. It’s one of those rare products you’ll wonder how you ever lived without.11/10 — total vortex domination!

Works great for mixing up those morning protein shakes after a hard grind at the gym. Works so much better than shaking and getting your protein all foamy.

Happy but... PROS: Quality materials. My second Voltrex and parts are interchangeable which is awesome!!. Blends well and holds a charge. I use mine every day and charge lasted a good 2 months and still had some left over before I regarched it. See through so you can see your drink which is different from my last one. CONS: The lid.. Flip top part has to be held down. If you don't hold it down, it will fall over disrupt the flow into another vessel (like a cup) and makes a mess. This was the reason for deleting a star. My last Voltrex did not have that issue. FINAL: Would I buy again? Maybe. I may go back to my older Voltrex, but this one holds a charge better....

It works perfect!! Husband has said after it’s done mixing there are no clumps! Was the perfect Christmas gift — especially for a gym lover! No leaks! Easy to clean!

The media could not be loaded. Love this thing! So far the battery life is great. I charged once and I’ve used it about15 times so far over the past month and still going. Hope that lasts. It does not leak, and there was no chemical smell.For success:Add liquid first (NOT powder first)!Leave at least 1.5-2 inches at the top so when it spins it doesn’t overflow.Minimal or no ice (can always add ice last and gently swirl manually)This is a mixer not a blender - it doesn’t have metal blades and is not as powerful - so it won’t blend fruit or chop things or crush ice. So don’t add anything that isn’t liquid or powder. Heavier liquids like heavy cream will work, but regular peanut butter, for example, probably will not blend unless already thinned. You could probably get away with apple sauce if you poured it in slowly to another liquid.It’s very easy to clean. Obviously best to clean before your drink dries in there, but even if it does, use hot soapy water and turn it on or manually shake it with the lid on, then just use your hand or something soft like a sponge-brush to get any remnants. The cup part unscrews for even easier or more cleaning if needed.Hope this lasts because it motivates me to have a special, nice product to look forward to using for my health drinks.

Ive previously only really used blender bottles with the blender ball which work, but every now and then there would be a bunch of unmixed powder. Never had that happen with these. Battery lasts a while and very easy to clean. Plastic feels like good quality and will last!

I do like this product. It can mix 2 scoops of protein powder with a liquid very well. There were no chunks of unmixed powder. I did try it again and I put a banana cut in pieces and the mixer failed to do a good job. I am pretty sure it’s not made to break down fruit but I pushed it to see what it could do. It did mix Kachava well, I can pack the powder separately and some water and bring this to work. That was my main intension. I would charge the battery everyday. On day 2 the mixer did struggle a bit. USB-C charging and cable is included. Made from durable plastic and can take a beating and not leak and will still work. Great for the gym bag or the beach bag. I didn’t have to contact customer service. I had this product for 1 month before I wrote this review.
