With a metal barrel, decent handle, easy to read gauge and dual head that's better in operation than the one sported by the £150 carbon Air Tower 5, the TP1 looks like a bit of a bargain. However, it's badly let down by its base; a creaky three-piece plastic offering held together with seven screws.
It's horribly flexible, and the worst base here by a mile. You'll need to be careful with it or you'll quickly break it. Everything else works pretty well, and though it's only rated to 115psi we're sure it can push a lot more than that. There's always going to be some plastic at this price, but it's better used in the piston of the Truflo Max Trax than it is in the base of this unit.
