While the Titan 18453 5-Piece Locking Plier Set offers a good variety of adequately-built tools (adjusting screws are a bit rough), the plastic grips reek of some type of petroleum-based chemical (gasoline or similar) evidently used in the manufacturing process. That odor soon spreads in a room or accumulates to truly nauseating levels inside a tool chest drawer. Household and shop cleaners did little to reduce the odor. Same with airing outside for several windy days. The entire unused set is now in a sealed plastic bag awaiting some form of final disposition. Return is unlikely since the original packaging was trashed (don't make that mistake).
