Question: How long is the warranty for the pump?
Document: This pump works GREAT! It has a very easy to read dial, and it shipped VERY quickly!Pump also has a lifetime warranty.
This pump works great, I purchased it because it works both on the Schrader & Presta valves with the same head and can pump to 160 psi if needed. It has a life time warranty so if it breaks you just have to send it in for a repair or replacement and just keep on pumping up those tires.
Used it on Presta to 110 PSI, still solid.I suppose Serfas is so confident in their product that they will warranty it for life, so as far as I'm concerned this IS the last pump I will ever buy. This is half the price of my Joe Blow, and better quality.
Lifetime warranty is a great plus!
The decision to get this pump was even easier for me knowing that it has a lifetime warranty. I was amazed at how quickly (3 minutes or less) I was able to inflate one tire. The pressure gauge worked perfectly. If you have a problem with the gauge I recommend that you either call Serfas or return it to Amazon and have a replacement sent out to you.
My bike tires use 120lb and it delivers and fairly quickly. Gauge seems to be accurate? I pump to 120lbs and haven't blown a tire. I should check after with a tire pressure gauge? I was surprised a pump at this low of price was so well rated. I have to agree - GET THIS ONE. And I believe it has life time warranty?
All in all it seems very durable for my needs and it has a lifetime warranty and was worth the extra few dollars over the walmart junk.
Easy to hook up to either kind of valve. The thing moves a lot of air. It's quick, and it's got a lifetime warranty. Very nice.
Stay away from this air pump. After only very light use, this pump stopped working. The built-in air gauge became defective, and now the gauge blocks the air from being pumped to the nozzle. There is no way to bypass the air gauge, and no way to remove the gauge. So now the pump is useless.I tried to contact the manufacturer via email to get coverage under their "lifetime" warranty, but instead got no response whatsoever.
Just press it onto the valve, and pull the lever into the up position and you're ready to go. For the price, it can't be beat, especially considering they offer a lifetime warranty.
Answer: yes
