Looks nice. I never had any problems with the larger video tools. We have the larger drain camera 3"-4" drains, and also the smaller for 2"-4" drains. They work real well. The smaller camera is hard to push down 4" drains if there is any problems in the line like a separation.
Hope that info helps you. With a shop of 7 techs they get alot of abuse and takes it like a champ.
