Review on 🍹 AIKIDS Portable Blender: 17Oz Personal Blender for Smoothies and Shakes - 4000mAh USB Rechargeable Mini Blender with 6 Blades - Handheld Blender for Sports, Travel, Gym by Greg Stevenson

I like the concept, the size, the portability and the fact that it uses a USB charger. However, my experience is that it often starts and stops, and then I have to shake it, open it often, and stir the contents. It often takes 3 or 4 tries before it finally starts and then I stop. I make smoothies with almond milk, frozen berries, protein powder, and some frozen banana slices. You also need to be very precise to line up the little red arrow on the "cup body" with the lights on the base. If you deviate a little, it won't work. Also, I like to drink straight from the cup, but the base is slightly rounded so it doesn't lay flat on the counter or fridge shelf. Maybe it was only meant for a juicer, but for my use it's not true.
