BikeMaster Extra Reach Adjustment Screwdriver

I bought this without realizing that the bit is not interchangeable. The bit at the end is a straight bit, so if you've got phillips screws, you're out of luck. It should've been designed with a magnetic hex end that way you could change out to whatever bits you already have for your drill. I wish the pic provided of the product could've been zoomed in on before I bought it so I would've realized this detail and moved on to the proper tool.
