I've had a problem with the road morph once, but topeak sent out replacement parts very quickly. Then when I was on tour something happened where it was leaking a bit and I couldn't get good pressure and unfortunately I had to buy another pump cause I needed it ASAP. However, if I had the time I am sure I could have sent it in and gotten a replacement. Topeak has great customer service, and that is what made me buy the mountain morph, the shop in the small town didn't have the road morph in stock. Anyway, I bet the owner of the shop sent my old one in and got a free new road morph.
Haven't had a problem yet with the mountain morph. No gauge, but that doesn't bother me too much.
