After reviewing many different tool bags the Veto Pro Pac MTC Blackout was the obvious choice for my needs. This is an honest review and purchased with my own money. I'm a nursery maintenance lead that performs HVAC and electrical wiring installation and repairs, plumbing repairs and installation, and carpentry. I have to carry a variety of tools for all the different jobs on the property and the Veto bag is small enough to carry with the included shoulder strap or the integrated carrying handle. When completely loaded out it became quite heavy so I purchased a Milwalkee foldable hand cart to move it from job to job. The Veto Pro Pac has highly organizeable removable inner tool holder panels that are held in place with velcro. I have a plumbing panel, an electrical panel, and a laptop panel depending on what job I'm doing I remove a panel and replace it with the appropriate tools already installed in the panel, what a time saver and organizer. This Veto Pro Pac isn't cheap but I looked at it as an investment, this is a top quality product that has made my job more rewarding by having all my tools organized and ready for the next job. When I look in the bag I can tell if there is a tool missing before I move to the next task, no more lost tools. Is this bag over engineered, yes but the quality and durability is well worth the purschase price. I highly recommend this for HVAC and electricians needing a tool bag that will endure the test of time.
