The image of the packaging and the web view does not match the product - Suffice it to say that before. In my opinion, the pump is easily assembled wrong! What do you expect from such a product and the price already?
When adjusting the pump to the "head" and inflated (and not too firmly stands on the round handle), then it's much better. If you were to stand the pump in the correct direction, the hose would move along with every up and down movement, perhaps it is then too short, or would slip out of the air mattress etc.
Everyone who occasionally need an air pump with neat volume and do not want to spend so much who can try calm with this pump. I can say nothing about the strength and durability. I suspect, however, that the pump not suitable for "continuous operation" or "undue hardship" is.
I give 4 points, because it works, a point deduction because of poor description and incorrect installation.
