Just fitted a tyre with the Airshot too – fresh tyre straight out of the box, so still with the fold kinks in, and it went up straight away first time – very impressed!
Could only get my ghetto inflator to 50-60psi before it started leaking everywhere, and there’s much less fear of the Airshot exploding and taking my face with it too. 😀 Bit expensive for a tin with a hose on, but well worth it for the reduction in faff!
