Just received and used on a low voltage wiring. The stapler doesn't get as close to the corner of the trimmed board where it meets the 90 degree turn, but it works very well on straight sections. I haven't clamped the wire yet, so this is a big improvement over using a flat brace for the wiring. If you need to connect low voltage wires, this is a good tool. The brackets are too small for ethernet in my opinion, although I haven't used them for ethernet. But for a bell wire and wire like that, you need that.
