The air pump looks solid and works very well. The bag that comes with it is also well made and holds all the parts well. The pressure gauge is also accurate and will stop pumping at the correct pressure. The ad is really good. Some ideas for future improvements: The control buttons are a bit confusing and it takes some time to figure them out. It would be nice if the next model had a larger main on/off button to start the pump. It would also be nice if the next model had a microUSB charging port to charge it with a normal cable. It would be nice if it had a USB port so the battery could be used to charge a cellphone.
