Review on Crescent CDTS6N Drive Internal Socket: Superior Performance and Durability for Pro-level Projects by Rick Kreutzer

Serves its purpose very well, got it for a filler plug in a sealed gearbox on a Mazda CX-9 (Tip: Remove the air box and attach the air tube/cap to to get better access to the filler screw holes); Transmission fluid had to be added, and of course the '012 has that idiotic transmission with no filler and dipstick; but this tool saved the day. A set of 3/8" Torx bits I've had for years didn't have T55 bits for some reason (get it). I don't understand why I need something better. Very reasonable price; looked at it and was tempted to buy a set of 13 end caps but i don't think i'll ever need half of them because i only do maintenance and repairs on my car i need fluid and what fluid to use for that crazy crossover. The drain plug and oil level plug at the bottom are the tricky ones. But I did it and saved some money which was my goal.
