I actually purchased the HV35 model, which appears to be identical, except painted red.The ultimate in functional simplicity.  Beautifully made---you could tell your friends that it is standard equipment on high-end Mercedes or BMWs and you'd be believed (but remember to take off the "Made in China" sticker).  Actually, the pump (in its attractive zippered black canvas case, at least with the HV35 model) will probably perfectly fit in the recess in the trunk of German cars (which is meant for the first-aid kit required in Germany).Having used the pump several times---it has worked perfectly, pumping up tires promptly.Unfortunately, you need to unscrew the supply hose to put the pump away in its canvas case.  A simple right angle connection would be an improvement.Note that you also have to screw-on the supply hose to the tire stem---there is no quick-connect connector.  Nevertheless, the connection and disconnection is easy---just a quick twist clockwise or counter clockwise---much easier than my experience with other less-well-built tire pumps with screw-on connectors.Initially, I do not miss the lack of a quick-connect connector.  It was the rubber gasket in my last air compressor which failed.  The two air-services at the two nearest gas stations to me are also equipped with defective quick-connect connectors---which I discovered the hard way.  So, I'm no longer a fan of quick-connect connectors.  But again, this little pump works great WITHOUT a quick-connect connector---maybe because the brass screw-on connector is made with greater precision and better design than most.Then I purchased a new VW Golf, and the connector will not screw-on to one of the valves stems.  The valve stems contains electronics and so is too expensive to replace.  So, I had a bright idea, I could use a valve extender as an adapter, and purchasedSlime 2045-A 1-1/4" Metal Valve Extender.  But the screw-on connector will not attach to any of the 4 valve extenders.  I strongly suggest that you actually check that the connector will fit all of the tire valves on your car.I've looked, but unfortunately screw-on to quick-disconnect adapters do not exist, nor as far as I can tell are replacement hoses which would fit this pump available.  The cheapest possible solution I've found isSunlite Replacement Pump Thumblock, Schraderwhich would require cutting off the screw-on-connector and replacing it with the "thumblock".  However, I haven't tried it yet.Since valve threads can be damaged, and the actual valves can fail, keeping a valve tool with extra valves with your pump kit could be a good idea.Slime 20088 4-Way Tool with 4 Valve CoreIt is also important to keep the valves clean, so a few spare valve caps are a good addition to a tire kit.Slime 22049 Black Valve CapIn general, dial-type air guages are more accurate than stick type; mechanical are more reliable than electronic (batteries fail); and I find straight stems much more easy to use than angled---getting the angled at exactly the right angle can be difficult.  So I recommend a dial-type pressure guage such as the 0-35pdViair 90056 2.0" Gauge (0-35 PSI) Tire Gauge with Bleeder Valveor the 0-100pdViair 90072 0 - 100 PSI 2" Tire Gauge with Bleeder ValveFinally, a little silicon grease is great to insure a good seal, and (like WD-40) is a must in every auto emergency kit.Permatex 22058 Dielectric Tune-up Grease - 3 oz.To see my "Put together a tire maintenance kit" and "Repair a tire valve" guides, click on "See all my reviews" above, then click on "So you'd like to know" guides on the left side of the page
