Review on Drive Chrome Long Socket Rail by Sean Spence

One of the biggest advantages of this set is that the size of the bit is the same from the socket to the end of the bit. Many other sets narrow down the smaller bits. For example, in other sets, a 4mm bit is actually 6mm (or more) until it tapers to 4mm towards the end. This is a problem for many of my applications where I can't use the 6mm cone bit to reach and tighten the 4mm hex screw because the cone is too short. These bits solve this problem. This set is very well made, with easy to read markings and a very impressive aluminum storage rail. The quality is much better than I expected for this price.
