The bits came in an aluminum case which seems to close tightly and the bits themselves appear to be very well made. I haven't had to get it working yet, but I'll update my review when I do.
For those interested in the brand, item #61686 is $8.49 on the site. I didn't see any of this information until I bought the drills. I suspect that this tempts buyers to buy something at inflated prices. This is a good product but it is labeled!
I got these because I had to remove broken screws. The screws were hardened and the surrounding metal was cast iron. I had to completely drill through the hardened screws. These bits really stood the test, only one lost part of the edge. This performance exceeded my expectations for bits in this price range. If you need left hand bits (and everyone should have a set at the store), get them.
