Got this for my son, he loves it. It is only a $20 mixer, people putting ice cube in it, no, that aint happenin, come on. Mixes liquids and powders on the go, when we want smoothies with crushed ice we take out the bullet, but this works great for on the go protein shakes. We clean it right away, all good.This product runs on battery unlike the similar one but different brand I had purchased that runs on charge. It has no strength even with brand new batteries, to mix my protein shake. I purchased this one because my last one overheated and melted the wire in the charge port. Other than that it worked so well. This one I hoped would as well and I was happy no wires. I bought two. One for me and one for my boyfriend to have our shakes at work or on the run. Neither of us can use it bc it drains batteries within two days and has no strength to mix. I threw money down the drain. I would have sent it back, but it was a used cup and I doubt they'd want it back.I liked it a lot because it is easy and practical to use, good purchaseI used it for protein shakes. I found 2 major problems. One of them is that after a while, the drink residue gets trapped under the plastic by the rim, which is not removable, can not clean it out, therefore stinks. I even soaked it in clorox, but had to throw it away after about 2 months.Secondly, the battery wears out fast, need to change every week, can be costly.Very quiet ...does a good job without being noisey. Perfect to take on a plane without fear of being annoying. Cleans beautifully. I have owned many small mixers, this by far is my favorite. I also bought one for a very picky friend...she loves it, tooThis is amazing for our powder energy drinks… Use this multiple times daily… Keep buying this item because we use it so much… Love itDidn't last long but for the price it was a fair productLove it but I wish it had more power
