This little compressor pump is great. I took some photos of the dimensions of the blocks in the bag (7" x 4" x 7" and it's nice and compact. These days things come in packaging that's hard to handle after the first unboxing) The pump comes with a spare fuse, needle, pair of cone adapters and some valve caps (nice as I always need a spare.) I'm a big mountain biker so I took this little guy on a weekend mountain bike ride. He showed himself very well. I particularly appreciate the fact that I was able to fine tune the PSI I wanted to inflate my tires to and the cone pump. at the advertised level. This makes him resistant to jerks (which I also appreciate) "I set the compressor to 35psi - and inflated my tires (and the tires on my girlfriend's bike) with ease. It was very easy and very quick. Just this morning I got the compressor pump to the soccer ball raining and used the threaded needle adapter for filling. balls to a predetermined pressure of 8.5 psi. Perfect. If I had to be picky - maybe I'd just change that being able to plug it into an outlet would be nice, but that's no big deal. You almost always have a car if you have an outlet. Also, it's advertised as a 12v compressor, so I get exactly what I paid for: a great little portable compressor. I definitely recommend it. I plan to buy a second one and have it in every car - "just in case". 5 stars for now (I've had it 3 weeks at the time of writing this) and I'll update my rating if anything changes. I will also update in a few months to see how this little thing holds up. Hope this review helped - definitely recommend this product!
