Need a cutter to replace the camera. This worked, but the hole size locking wing nut is not well designed. It slips off when you tighten it by hand. I had to use pliers to make sure it was secure.
Bought a little over a month ago and found a "used in good condition" and decided to save a few bucks. Ever heard "buy well or buy twiceβ? Well, I haven't learned it yet. The one I received is broken and in fact I'm already 2 days past the return window. It's not about the money. Just the fact that it ruined a rare day off to work on my project.
This tool is the ticket. I've been in the maintenance business for about 40 years and it keeps in my "favorite tool" drawer. I took on a project to replace and upgrade my home HVAC system and without it I would have had a lot of snips from metal shears. If you work with air ducts and like professional results, get one of these. Great tool!
