The measurement markings are clear and easy to read, which makes mixing supplements precise and hassle‑free., no extra parts to clean, and it mixes my drinks smoothly. Leak‑proof, durable, and perfect for everyday use. If you’re serious about fitness or just want a dependable shaker for daily use, this one is a must‑have. Highly recommend!

This thing is awesome. I’d been taking Protein and using a spoon to stir it in. A lot was being wasted by not mixing completely. This has solved that. It perfectly mixes the water and protein or milk and protein. It is also super easy to clean by filling it almost to the top with water and adding a drip of water before running the mixer. After 30 seconds you just dump and rinse. The battery is also pretty good. I mix at least 15-20 times before the light turns red. I usually mix about 3-5 more times once it is red then plug it in. So you shouldn't have to worry about it being dead, if you bring it with you. It charges pretty quickly too which is great. Highly recommend!

I have to mix formula everyday for my PKU. It comes in a powder that I put in the cup first, then add the water in after. Give it a couple shakes then turn on the mixer. It mixes well! No more powder clump surprises while drinking. To wash, the base comes off and it is wide enough to stick a rag in to wash it out easily. I was pleasantly surprised with it.

Love this blender bottle. It mixes my protein powders perfectly. Keeps a charge for several days. Easy to clean

Durable. Quality plastic material. Cleans easily. Easy to use. Looks good. Good price. Good size. The only thing I don’t agree with is the fact that they said you can mix up to 200 times in one charge. That’s false. I was able to get about 30 uses on one charge. I use it once per day in the morning. Had to recharge in a month.

I have been using this for 3 days and loving it. I have shaker bottles but they are not breaking up all the protien and collegen powder. Hate that I am wasting the powder by dumping clumps of it down the drain. This little fancy dancy little Voltrx is amazing. Pour a little almond milk in, put my powders in, pour a little coffee in and hit the button. While it is whirling and doing it's thing I'm getting ice in my mug, grabbing the lid, back to coffee counter and the blending is done. Pour over ice and not one clump, no icky gooey clumps on the blender part, and simply no waste. It is the best. I do have one complaint or maybe one suggestion that we could purchase an extra bottle with out the whirly part. I rinse everything after use, but would like to use another bottle to mix my afternoon drink with while my earlier one is still dirty. My next thought is I wonder how this would work scrambling eggs. I will try and find out.

I love this cup. It is well made, very easy to use, mixes everything well. Nice size. Easy to clean thoroughly. Great customer service too based on my experience.

Update 6/25/26 - The new shaker bottle that was sent to me by VOLTRX at the end of February just stopped working after nearly 4 months. Yesterday, it wouldn't turn on because the battery was dead (even though I had just charged it a few days ago - normally I just need to charge it once a week and it's fine). So, I plugged it in and then it was taking a charge. I was also able to turn it on and it worked. But then it wouldn't stop. I could not get it to turn off right away. It eventually stopped and I plugged it in for a few hours so it would be fully charged. When I turned it on this morning, it was dead again and wouldn't even charge. So this shaker bottle is once again useless for it's essential function of mixing up my morning supplement drink. I tried to reach out to the vendor, but their support link is not functioning. Guess their website works as well as their product. ;) I am dropping my rating of this product down to 3 stars. The bottle is great when it actually works. When it suddenly stops working (and it will - this is my 2nd one within 1-1/2 years), you end up with a tumbler with unusable accessories. I will not be purchasing more VOLTRX products in the future since they don't seem to last very long. Update 2/28/26 - Just a few days later and I received a brand new shaker bottle to replace my old one. Very impressed with the customer service. Updated the star rating to 5 since I love the shaker bottle. I bought this in Nov. 2024. I have used it nearly every day since then to make my morning supplement drink. I love how I just push the button and it mixes all the liquids and powders together and doesn't make a mess. The bottom base detaches so it can be cleaned by hand and the rest can go in the dishwasher. I normally would just have to charge it once a week. It was working fine until about a couple weeks ago. The battery wasn't holding a charge very long and I had to start charging it in the middle of the week. And now this week, I have had to charge it every day. This morning, it wouldn't turn on at all, even after having charged it yesterday. So - gasp - I had to shake up my drink by myself! Not the end of the world, but when I bought this bottle to do it for me automatically, well, it is no longer as useful. Before the battery malfunction, this bottle was great. No leaks, very portable, and decent quality. I guess that's why I'm less than thrilled right now. I did send a message to VOLTRX about my issue, so now I'll wait to see how they handle it. I will update if I hear back, and possibly update the star rating, depending on how they respond.

Very good product 👍

I love this shaker, particularly in the beautiful green colour that I got. It’s very simple and functions extremely well and I believe it’s well designed. I use it every day and have been using it every day since I bought it. My only worry reading a few of the other reviews is that the motors won’t last very long and so I will come back and update my five star if problems arise in the next few months., however currently I’m loving it Can recommend. Edited: 18th July 2026. 3 months of daily usage. I thought I would revisit this review because I am a fan of this shaker, there don’t seem to be any contenders in this niche on amazon and I intend to buy another one if ever this should fail. Three months of day usage and shaker is still in good condition. The seals are intact, the screw threat on the bottom is fine, the motor/battery/gearing all function correctly. So all of that is a positive. I did have a moment of panic a couple of weeks ago when the gears seem to have gone, but I believe it was to do with me charging it by mistake with a fast charge cable. I could be wrong, but it’s the only thing I can think of that would’ve affected the performance momentarily. Once I recharged using the original cable, everything went back to normal so that was weird. I’m not an electrical engineer or an engineer at all, so I would have to defer to the manufacturers as to why this possibly happened. So there you go that’s my update. I still recommend this great bit of kit and with the competition being non-existent seemingly I would buy this model again but hope it will last me another three months.
