I haven't actually put this tool to work yet, but it's one of those things I've wanted in the toolbox for a long time. Every time I find myself fighting with a fastener in a tight spot, I end up thinking, "I should really get one of those offset adapters."
First impressions are excellent. The tool feels solid, has a good amount of weight to it, and the alloy steel construction seems built to handle real work. The included drive adapters are a nice bonus and make it versatile enough for a variety of projects.
The design looks perfect for getting into those awkward spaces where a drill, ratchet, or impact driver just won't fit directly. I can already think of a few automotive and DIY projects where this is going to come in handy.
Even though I haven't used it yet, the quality is impressive, and I'm glad to finally have one in the toolbox for when the need arises.
