Yeah, the Topeak is a really great little tool. Perfect for a light EDC toolkit (and I find myself going for it even at home at times). I have switched to the similar Victorinox ratchet but that's mostly do to how well it carries in the Spirit sheath. In general I think the Topeak version is the more user-friendly tool due to things like the direction switch and how the ratchet doesn't allow the bits to go right through.
Yeah - not handled a Vic ratchet, but the Topeak is nigh on perfect as an easily carried EDC - that, and the Vic 'L' wrench with bit holder and the small adjustable spanner I carry covers an enormous range of tasks for hardly any weight or pocket space. Add the Spirit and I rarely have to grab anything else from the workshop aside from a drill saw or hammer.
It's a really well thought-out tool and super robust.
