This was significantly smaller than expected. This is not a bad thing, just not expected. Seems slightly less durable than a full sized air pump, and would be nice to have a built in pressure guage. That being said, it's somewhat compact but works as good as any full sized pump I've owned. It also has a small plastic container that snaps on the pump to hold the various nozzles, which is a nice touch. Overall, I like it, just wish it had a pressure guage on it.
