Anyone using this tool link or something similar?

Yes. I have used it many time but not for your typical Ma and Pa installs only in Data Centers and other High End data rooms where the velcro matches the cable.

Time consuming but if that's what the customer orders, I'll do it. Makes nice waterfalls too.

This is the one that I bought years ago. I don't do much cabling anymore, but it is slick. Put the outside cables in the comb, put the rest of the cables in the center and dress away. Keeps the outside of the bundle looking nice, you don't really care about the interior of the bundle.

I use it all the time for my cable installs. Works great with no issues and none of my installs are in data centers.
