I switched from a small open top CLC bag to the Veto Tech LC. I love it! I am a roof rat and hate making trips to the truck. Yes it is a little heavier but it sits nicely on the little dolly that I use to haul my filters around. Also I have been working in the misting rain for the last two days changing out 17 hail damaged condensers, my bag is wet but my tools are staying dry. I'm sure they wouldn't be as dry in a pouring rain but, they are drier then in my open top. Two thumbs up from me!!!
