Airace’s 20 in 1 Ultra Thin multi-tool offers some good quality Allen keys (2 to 6mm sizes) with a snap-on 8mm head. Other tools include Phillips and flat-headed screwdrivers, along with the essential T-25 Torx key. The detachable section has 8, 9 and 10mm spanners, spoke keys, a chaintool and additional 3mm Allen key.
We did need to tighten both pivot spindles on the main tools because they became loose quickly, leaving Allen keys and screwdrivers flailing about. We also lost the snap-on 8mm head within weeks too, which is quite annoying considering the price.
