A couple of things that don’t translate well in the photos: The midnight hacker is tapered in the center and has a powder-like finish; it has great hand feel and your bump key won’t scratch up the finish… The spring action is incredibly solid, too, with a nice little tactile snap when extending and retracting tools.

I love my Squirt E4, but I’ve always been bothered by the fact that it’s so hard to clean.
I’ll definitely be picking one of these up when I grab an Arduino Uno.
