I was initially attracted to the price. But at the same time, skeptical. I've been through pumps around double the price that have reduced in performance or failed after a handful of uses. My last pump was a dual chambered type mini from a reputable company and it failed after the first use. I like pumps that have a high flow. I want to be back on the road as quickly as I can. I finally had to use this pump and it didn't disappoint. I've used it on my SSCX with 38c tires in the middle of a race and my road bike with 25c. I got my road tire inflated to 90 psi fairly quick and was back on the road. And if/when this pump fails. I'll happily purchase another one without hesitation due to the price, coupled with performance. Dang good value overall and I highly recommend.
