I put that is easy to use, but not if you read the instructions since they are wrong hehe. You need to push the button 3 times, not hold it for 3 second, for switching it on. I was about to return it saying that wasn't working.
Jokes aside, this little electric pump is really handy. Will make much easier inflating the air beds and the paddling pool this summer. It is also good for vacuum clothes bags! Really easy to charge and use.
