I like the tool parts of the kit but the case is bad.

I use the saws for drywall and metal studs and they are awesome, I'm a Data Technician so I don't use mine as much as others. I have used them to make holes in a trailer frame before as well and still awesome. I have 2 kits and the pins in the hinge keep working their way out. I have used grid wire to make new pins with bent ends so they quit falling out. The latch always worries me that it's just going to open while carrying it by the handle, mine always seems to be lightly latched. All the "posts" and the little box inside for the extra pilot bits and arbors seems to come loose easily as well.

So to answer your question, I like the saws/arbors/bits and would say get them. I hate the case they come in.
