I don't know if this set can be called "Precision" other than all the bits are small (precise?) and the set is clearly designed for that Working with various electronic devices. Many sizes and shapes are included, from flat to torx and more. There is also an extension for the handle so you can reach deep places. (Note that special "security" bits are not included; you'll have to buy them elsewhere.) The kit is cheap, not very well made, and not designed for heavy use. However, this is more than enough for light work with electronics and given the nature of such work, they should last a long time. The case is good (just don't drop it), but there's one thing to watch out for. Per. There are many bits. When delivered, the bits are covered with foam so that they do not fall out of their holders in the case. Save the foam and use it again! And keep it right! When the pieces fall out, you'll have a great time trying to put it all back together. I would still give five stars for the value for money. Very convenient and convenient.
