so finding tools alone the way to get things done faster can be hit and miss. not to advertise this too much but its something I have found that works very well for small things and on the go. this little guy is not the most powerful thing but is great for hard drives, with it it takes less than a minute to strip a hard drive minus the times the magnet sticks to it lol. the bits it comes with are ok but the precision bits from walmart or some kits you can get online fit this not all of them but a lot of the ones you get will. I put up a ebay link for this but you can find u.s. sellers for about $20 cheaper depending on were you look.
thought I would post this as a fun tool to use and I bought 4 more after I put the first one to use so I do not have to change out bits all the time.
