This portable blender is perfect to have for on the go smoothies. The blender base has rubber feet that grip so it doesn't slide. The charging port is in the front so no hunting for it. Easy push button to turn it on and to use. To attach the blender cup to the base you have to twist off the cap on the base. This reveals the blade. Becareful as they are sharp. I really enjoyed this because the cup has a lid and a strap. The strap on the side allows you to carry it. The lid has a lock so it doesn't leak. So what you have to do is slide the plastic piece down then push the rubber button and it pops open. This reveals the drinking spout.
