I just returned from the deep woods and found that this pump was an absolute essential item to the trip. It took me less than 2min to fully inflate a full sized mattress.

When coupled with the coleman 4D pump, it took only 6min to fully inflate a king sized bed. The two pumps together were a perfect combo. If you are inflating more than one bed, you can use the battery, or car pump to get the beds to a certain point, then use the manual pump to finish the job. This pump comes with a variety of nozzles for every bed type in the coleman line, so you wont have to worry about being without comfort or having to look for other accessories.

When it was time to deflate and pack up, I found that by placing the hose on the other air point, I could suck the air from the mattress easily and get it to the point where I could roll it back into the bag without hassle.

I would highly recommend this pump for all coleman air mattresses. 5 stars

This pump works great as a backup for our electric. I'm always afraid the electric one will die on me, so I got a manual one. It's easy to use, and fills things really fast since it pumps or sucks air on the up and down stroke. 5 stars

This is the perfect pump for an air mattress. It comes with other attachments too. It's easy to use and the best part is NO BATTERIES required! I'd recommend this to anyone. 5 stars

This pump works great. I was looking for a non electric pump because I did not want to be relyent on batteries. 5 stars

This is a great pump that works on both the up and the down pump stroke, allowing you to pump up your item in half the time. I purchased this for a Coleman 5-in-1 air mattress and it works perfectly. Not as fast as an electric pump, but you never have to worry about it running out of juice (unless you pass out from exhaustion). It does take a while to pump up an air mattress, so I wouldn't recommend it to people who have a heart condition or people who need to inflate a lot of large items at once. 4 stars
