As a result of my tests I determined that the wrench had below-average durability and felt cheaply made. While the ball L design was helpful for accessing hard-to-reach angles, the steel didn`t hold up well under pressure. THIS wrench might suffice for occasional use in a hobbyist's home workshop, but it's not suitable for regular or heavy-duty industrial work .Its low price and availability may be tempting, but trust me, invest in a higher quality option instead..
