"If like me you want everything done as neatly as possible and quickly, this is a must. It's far easier than cable clips and you can hardly see the staples when you are finished, also the ability to staple your cable right into the corner is a bonus. It's not a cheap bit of kit, but if you find that in replacing skirting boards, door surrounds etc, you need to put back existing cables then it's money well spent. Goes into hardwoods, softwoods and even holds quite well in plasterboard. All in all a good addition to the tool box. Have rated high on reliability, purely because it is extremely robust and I can't imagine it will ever fail."
