I have had two different brand. The first was a deep bottom Kobalt with a coffin type lid and push button open. This box was really just too big, I ended up just accumulating junk and anything that went in the bed could barely slide underneath. I wouldn't get another push button open either, once it got some age it wouldn't operate without constant lubrication. The one I have now is a shallow bottom and low profile lid from tractor supply. This one has the black paint coating. I bought this in hopes of cutting down on the aluminum dust that gets on everything. It did help some but dust still accumulates. I wouldn't buy another all aluminum one, it ruined a lot of stuff with the dust. Mainly from the plastic tool tray sliding back and forth. If I got one the tool tray would come out and I would spay the inside with the DIY bed liner spay. All-in-all I'd buy another black low pro from tractor supply. It's been a solid box.
