For precision routing nothing beats a small handheld router (aka laminate trimmer, palm router, trim router). I use one for milling hinge mortises, flutes, inlays, butterfly keys, grooves and rabbets; for edge profiling; and for trimming veneer and solid wood edge banding. They're lighter, quieter, and more manoeuvrable than their larger siblings.

The Bosch GFK12V-25N is powered by a 2Ah battery and features a brushless motor that delivers a no-load speed of 13,000 RPM, which I found sufficient for the 1/4" router bits it's designed to use. You'll only run into problems if you use dull router bits or too great a depth of cut. Use shallow passes (especially when milling dense hardwoods) and let the router do the work.

I found that the unique "L" shaped handle design adds a great deal of stability. In use, the center of gravity is offset to one side of the cutting edge – away from the edge of your work – while your hands are located above the bit. Because it entails a different way of holding the router you'll likely find, as I did, that it takes a bit of time to feel comfortable using this router. The GFK12V-25N is designed to be used with two hands – one hand positioned on the handle over the router bit, and the other hand applying pressure on two serrated gripping pads on the base plate. Because of its compact size and the ease with which it can be manoeuvred, I find that I'm constantly tempted to use it with one hand.

Unlike the Bosch GKF125CEN, which has a more conventional round base with a clear sub-base, the GFK12V-25N, with it's opaque and much larger base, doesn't afford as clear a field of view of the cutting area. Which means when you want to view the cutting action you need to bend over to view it from the side of the router. Somewhat inconvenient. 
Installing or removing a bit is a straightforward 3 step process. Press the button that releases the base (it drops the base down about 1"); pull the red bar above the collet out (to lock the collet in place); and then insert the bit and tighten it with the included collet wrench.

You can fine tune bit depth by turning an adjustment dial below the base release button. Each full turn of the dial lowers or raises the bit by .04" (just under 3/64").

At just over 3" by 5" the ABS base provides a good bearing surface that adds to the overall stability of the router and helps make it easier to control.

Bosch 12V stick batteries don't have on-board fuel gauges, so I was glad to see a fuel gauge integrated into the body of this router, as it's a convenient feature that I always use.

The GFK12V-25N doesn't have a dust collection port and it lacks a plunge function, both of which I can live without. However it also doesn't accommodate guide bushings. Perhaps Bosch will resolve this with a replacement sub-base at some point in the future.

After getting used to the unique handle design, and not withstanding its limited field of view, I found the router a pleasure to use. It can handle a myraid of edge trimming and light routing jobs in the shop and on the jobsite. Just as important, it's unique design provides exceptional control for precise routing. If you're thinking of getting a small, handheld router, then you won't be disappointed with the GFK12V-25N.
