Just got my hands on this 13-piece nano socket set and wow, these little guys pack a punch! The compact size (shorter than standard sockets) makes them perfect for tight spaces where regular sockets just won't fit.
The quality is top-notch as expected from Astro - forged CRO-MO with laser-etched markings (though the stamped ones are a bit small, but hey, there's not much real estate on these mini sockets!).
Love that there are no skipped sizes from 4mm to 15mm. The 11mm hex outer surface is genius - lets you use a wrench when needed. Already used them with my M12 impact driver and they're game-changers for cramped engine bays.
Only minor gripe? Wish they included a matching ratcheting wrench like their 3/8" set has. But at this price point with lifetime warranty, I'm not complaining!
Pro tip: If you work on bikes or tight machinery, these should be in your toolbox yesterday. They've already saved me hours of frustration on jobs where space is limited.
