Review on 🏋️ High-Quality Electric Protein Shaker Bottle - Tritan Material, BPA-Free - 20OZ Mixer Cup for Protein Mixes, Shakes & More - Battery Operated with Upgraded Design by Jose Guzman

***Update**** Completely stopped working after 3 months. I am very sad. I really liked this cup. I've had it for 2 months now with no problems and I love it. I use it to mix powdered smoothies with water. This is much better than using a shaker/beaker. I don't kill my hand and can do other things while this mug mixes for me. I do 3-5 pieces a day, that's enough for 3 days without recharging. I do notice that I lose some powder if it gets stuck on the blender's "blades", but it really doesn't matter much compared to the clumps I sometimes get from shaking by hand. I try to be careful when washing the lid as the charging port lid seems a little questionable on how well it can hold water, but no problems so far. I hope this lasts at least a year. It has a lifetime guarantee, but I'd rather have something that lasts. My only issue was not being able to remove the coaster from the mug and the instructions say it should come off so it can be washed. I didn't want to risk breaking it so I gave up.
