Well, I used to have a Topeak Road Morph/G, but the one time I needed it, the guts were missing. Since they were going to charge me for replacement parts (when it seemed like everyone else on these boards was having similar issues and being comp'd), I just bought something that looks like a pump from Wally World. Got no idea if the thing even works- I just make sure I use my floor pump to top off and I'm good..... which means on my next ride I will probably double flat and have a defective spare tube for mocking the Diety of Flats.
