Picked up a 'DieHard' low profile 1/4" socket set yesterday... Not bad at $42, but was hoping it would be compatible with my Astro Nano 1/4" and Wurth 1/4" lo-profile (11mm wrench style) sets. Alas it is not.
Neither the Astro's or Wurth's will even fit in the DieHard wrench (close, but not cigar) and the DieHard sockets fall right out of the Wurth and Astro. Note that the Wurth and Astro are fully interchangeable with each other.
DieHard isn't a bad set, big range of sockets (4-19), but not being compatible with my other sets makes it kind of a skip for me. The case is pretty cheesy as well, kind of a hard. likely brittle plastic that you can tell will not hold up very well.

Video review should release on my channel later today or tomorrow if interested...
