Review on Drill Warehouse Magnetic Extension Socket by Brian Healy

These aren't the best bit holders you can buy, but they're worth it for 10 usable bit holders for $8.99. Less commonly used tips so they're installed and ready to go without wasting $5 on a tip you can only use a few times a year. They're also great for borrowing tips, so it's not the end of the world if you don't return them. The magnets are fine, hold the tip and most screws well. The case they came in is actually perfect for holding my good bit tips and bit holders, but I had to make a small channel. Secure it with tape so it won't pop open in your tool bag.
