## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Good for the price, but tolerances a little bit loose.
  

*by M***S on Reviewed in the United States on July 12, 2014*

For the price, this is a pretty good set (4 stars takes the price into account).  I have used it quite a bit on my motorcycle and it has worked great.  I think the tolerances might be a bit loose though as when I tighten a bolt a bit with it, the bit gets stuck in the bolt and will pull off the socket driver (spring loaded driver, not a button locking one).  I shouldn't be tightening bolts with a ball end anyway, but my ball end set of allans (full size, not hex bit) fit tighter than these and are able to tighten much tighter than this set can and not get stuck at all.This set is good for reaching into hard places, or just quickly turning a long bolt with a drill, but make sure you turn the drill clutch all the way down so that you don't damage the bolt or get the bit stuck due to the loose tolerances.

### ⭐⭐⭐⭐ 







  
  
    Nice Ball Ends
  

*by P***E on Reviewed in the United States on July 7, 2011*

*(updated, see asterisked note)For the price ($10), I don't think there's currently a better set on Amazon (7/2011).  The tooling on the ball heads is crisp and tight, and the heads fit all of parts I've used them on.  The chroming looks pretty smooth and unblemished.  The 1/4" drive 7,8,9, and 10mm sockets have ball-detent grooves machined into the drive interfaces, while the 3/8" drive 3,4,5, and 6mm sockets do not.  While there's no grooves inside the smaller sockets, my 3/8" Allen and Craftsman ratchets and torque wrenches detent the drive interfaces snugly, and with out much play.  For a slightly deeper reach than the Craftsman equivalent, the 3,4 and 5mm ball head shafts have been machined to their respective diameters 10mm down from the balls' ends to their shoulders. The included rack is pretty handy, though, the 4,5, and 6mm have a permanent home in my shop apron.  My only gripe, and it's a real small one, is the size indication numbers are only 2mm tall, tiny.  To remedy that, I've color coded the 4,5, and 6 with some vinyl scraps I had laying around the shop.I have not compared these too closely to any other brand of ball end socket, though from what I remember from a recent trip to Sears, the actual machining on business ends of the tools seem to be on-par with Craftsman.As with ANY ball-end hex, bear in mind that the tool/fastener interface is reduced.  This reduction may cause problems in the form stripping out fastener heads, especially if wrenching on soft metal parts, such as aluminum.  It may be a better idea to use standard hex drivers to set your final torque.Pros:Good tolerancesDecent chromingIncluded rack100% Lifetime warrantyReasonably pricedCons:Tiny labelsNo detent grooves in the 3,4,5 and 6mm sockets*(update) Quasi-Con:The tool-steel part of these rusts pretty easily, keep them lubedBottom line:Great set at the price

### ⭐⭐ 







  
  
    Very weak
  

*by R***S on Reviewed in the United States on February 5, 2019*

I was not real happy with these.  I had a very stubby ratchet wrench and when I was  loosening an Allen head bolt the ball of the Allen wrench twisted off!  You might think that I was a  applying too much Torque , but that is not the case.  It was a very stubby ratchet.
