Lo he tenido por muy poco tiempo pero hasta ahora se me hace un muy buen producto, excelente relacion costo-calidad. Lo recomiendo!

Works well - good buy. We've had this for 2 years now and it still does a great job of pumping up the tyres on our bikes. I love being able to check the pressure of the tyres to make sure we get it right. Extremely quick to clip the nozzle onto the tyre and the pump action is v easy - and there's a small area at the base which you can stand on when you're pumping up your tyres which makes the pumping easier - very clever design.

Good brand name tested and durable.

So far, I've only used the pump on tires with Schrader valves, so can't comment on how it works with Presta. I bought this pump to replace a pump that failed (handle broke off) while I was attempting to fill my road bike tires past 80 psi. That pump was from a company with a four-letter name ending in "LL". The Topeak Joe Blow Max easily pumped the same tires up to the 100 PSI I desired with minimal effort. On the downside, because of the narrowness of the barrel, it takes many strokes to air up a 26" MTB tire to 65 PSI. If you ONLY fill large-volume tires, you'll be better served by a larger-diameter pump.I don't understand the shade thrown at this (and other) pumps' "inaccurate" gauges. The PSI scale on the gauge is only marked in 5-PSI increments, so I think the gauge is expected to be used as a general indicator of when you're nearing the pressure you want. I found it to be 2-3 PSI off (interpolating between the gauges markings) when compared to a know-accurate gauge.While it appears to be overall a quality piece, I worry that the plastic lever to clamp the head to the valve might break from stress over time; that's why only 4 stars for the sturdiness aspect.Other downside, and this has nothing to do with the pump itself: It was shipped via UPS, and arrived with the box almost fully open, and no packing materials whatsoever. I don't know whether it was simply thrown in the box and UPS did their usual thing (I have literally never received package delivered by UPS that wasn't damaged in some way) or all the packing fell out of the box after it came open. The pump itself was undamaged though, so I kept it and am using it. Note to vendor: Please try & find another way to ship!

Den är mycket bra och enkel och använda
