I just received this pump today, and have used it only once, but I have to say it has made an excellent first impression. It is very nicely presented in a box that would do credit to an expensive wristwatch. The whole thing exudes quality. It comes with a short charging lead, some valve adaptors, instructions and a protective bag.
The pump body is made from black anodised aluminium and is reassuringly heavy. There is an LED display that shows all the relevant settings and some buttons to change those settings. If an air pump could ever be described as 'beautiful', then this is it! It arrived fully charged and ready to go.
I can't comment on how well it will hold up over time, but I am optimistic based on the feel and weight. Only time will tell though.
Note to Engwe: Take better photo's! The ones you have really do not do this product justice.
Five stars.
