Bests & Worsts Reviews from Amazon

I'm really torn with this product. It's size an simplicity makes it a great fit for a small bike bag. It saved my bacon twice. But then the third time I tried to use it - the time I REALLY needed it - the puncturing needle fell out rendering it useless and me stranded. The two times it did work I was using a Presta valve. It worked really well. The third time was a Schrader valve and I really struggled to get it to fit. But then it broke, so kind of a moot point I suppose. I really doubt they will replace it. Not sure if I'm going to buy another one or look elsewhere. ***UPDATE*** - not even an hr after posting this review (on a Saturday) I got an email from Mike offering to replace the faulty unit. AMAZING service!! That earns this a 4th star!
