excellent quality for the price point, no more or no less backlash etc in the gearing than many other "higher quality" units that i have looked at and also used, few of the edges on the machined surfaces needed a lick with a file to reduce the sharp edges to my liking, and i found the jaws in the chuck a bit snug initially, so upon removal all surfaces were deburred and improved their function dramatically, but that is just a caution thing as i will be using it to teach a junior and want to minimise the risks as they are learning and still have 'electrician soft' hands.. certainly recommend this unit to anyone looking to add to their arsenal, and the delivery speed was fantastic. can't beat the quality for this price bracket considering the competitors pricing for the exact same size unit is almost triple the price!! even without the postage, so the half an hour spent deburring some fluffy edges makes it streets ahead in my book.
