As a freebie with the tent, it's good. Not worth the cost to buy outright. It works well, has aired up my tent twice with no issues. The ability to set a desired pressure is very convenient.

I don't like that the 12VDC is hard wired, takes up all the onboard storage. The button press length is strange, but worked it out.

We received this with our order as a "gift" to try out. We haven't used it yet but look forward to using it to inflate our tent and other items during our shake down camping trip with our Zonkoo Vega!
