Top critical review
Very long and would be OK used 'straight-on' but at an angle they may not grip...
on 8 July 2015
Bought these to get at a couple of tricky to reach bolts on the oil sump of my car. Whilst they were certainly long enough to reach, the angle I had to use them at caused the ball end to slip within the bolt. Ultimately used a set of Bacho hex keys with pliers to undo the bolts.
I reckon they'd be just fine if you're using them straight-on with the bolt, but at an angle you may struggle to get them to grip, especially if the bolt's tight.
