Good box line is strong but probably middle of road line wise box itself is great. Chalk load door is perfect sized and placed. Handle is nice size of box is great but my hands are xl caution if line wears through dont wind intakes a bit to resting if it gets pulled inside. I like color because you can find it and no one else has it.
