I bought this thinking it was a ratchet set but it wasn't. Also, the connector pins are only held by a tiny ball and the aluminum fastener falls off within seconds of use. Complete garbage. The tools suck, but the heads are good.
Pros
DOUBLE HEAD DESIGN: Features a dual head head design: 90 degree head (L-shaped) provides ample leverage to work with rigid parts; The straight head helps a lot when working in tight or difficult places.
