Yes! Nice little setup once installed.
The only trick to putting them in (other than the tight space working by braille) is to make a template out of cardboard or similar material to properly center each transducer between each pair of strings under the saddle. What I do is cut a piece and write "UP" on it and then using the outermost bridge pin holes as index points, punch the cardboard so that it can be fitted over the pins from beneath.
While set in place on the outside, draw a line across in line with the bridge, and three "X"s at the centerline of each of the string pairs.
Temporarily affix the transducers on each of those marks with double-sticky tape (clear so you can see your marks) with the surfaces to be glued to the guitar facing up. Trim off any excess cardboard that might run afoul of any bracing etc that you feel inside.
Then all you have to do is to insert two of your bridge pins to align the guide you have made, apply the adhesive and get it all inside through the sound hole. Align your template to the pins and press them in place before the glue dries. You can tuck a folded towel or sponge in there if you like to hold it for awhile and after the glue is set, gently peel your cardboard guide off the pickups and route your wiring to the strap pin/plug assembly.
When drilling the hole for the plug, I use a "brad point" drill bit, although a Forstner would also cut cleanly. I suppose a brace bit of the proper size would do as well if you wanted to do it carefully, but either way you would like to keep your feed pressure low to prevent grabbing and splintering the exposed wood grain. Hence the drill bit that cuts the perimeter of the hole first makes a nicer cut.
