5.0 out of 5 stars Small but powerful, November 21, 2007

This little air compressor takes up very little space and took me from 28-35psi in 30 seconds for each tire. The carrying case is very handy and fits everything in there without any force. Package came with a tire guage and attachments to inflate bikes and mattrasses. No regrets here; beats waiting in line at gas stations for air.

5.0 out of 5 stars Little Air Compressor that Could !!! Wow !, December 8, 2007

This review is from: Master Flow MF-1040 Cyclone High Volume Portable Air Compressor (Automotive)

Tires were running low on air during the cold spell and this little compressor came through ! Small and lite weight its just what the doctor ordered. This unit is easy to hook up and operate. Air gage is attached to read while filling. Unit is made of mostly of steel and not plastic. Unit does not walk away when turned on and is extremely quiet. This is a tool and not a TOY !! 10 foot cord plugs into cigar lighter anywhere for ease of use. 16 foot air hose is great. Total of 26 feet from cigar socket. Case is a nice touch! Takes 1 minute to fill tire. 30 liter per minute flow rate. For cars this unit is great ! If you have a RV or truck you may want to upgrade to 1050. Over all I would rate this unit A+++++. J.T.

3.0 out of 5 stars Quick, quiet, but with one major design flaw, January 18, 2009

This review is from: Master Flow MF-1040 Cyclone High Volume Portable Air Compressor (Automotive)

This inflator is well designed, works quickly and quietly, and comes in a nice storage bag to stow away in your car. It does have one major design flaw which is the purpose of this mini-review : the screw-on valve adapter. Most inflators come with a quick-release type adapter. This one comes with a screw-on adapter. It's good because it means a secure seal, but it also means that it lets a good 2psi of air back out of your tire every time you unscrew it. The problem is that as you unscrew it, the seal is broken with the valve, but the pin in the valve is still held in so air begins to escape. If you're quick, it lets out about 2psi. If you have large fingers, are elderly, or otherwise slow at manipulating small objects in tight spaces, this could let out up to 10 psi while unscrewing it. This makes the whole inflator questionable because whilst the built-in pressure gauge is bang-on accurate while the hose is attached, it's meaningless once you unscrew the valve adapter and let a bunch of air out. In the end you will find yourself over-inflating your tyres by 2 to 3 psi just to compensate for the screw-on valve adapter. It's a shame because otherwise this is one of the best inflators I've owned.
