      A:  This is a personal choice. Both are well made. IMO, just depends upon your response to the Domed level vial feature on the Johnson box level. I'm old school, and prefer the Stanley.

          poor packaging
          I recieved a 4’ level that was packed in an oversized box with no packing material to protect it. The box was crushed. Im not sure if the level was damaged or not. Not a reflection on the product but rether the packaging and shipping

            Great product at a great price
            This Stanley level is a great replacement for the one that I dropped just a few too many times. It is very lightweight and very easy to read the bubbles. Whether in a bright light or in a dimly lit area, I enjoy working with this level. There aren't really any bells and whistles to rave about as levels are pretty basic tools - but for all the reasons listed, I really like this level when my 2' one just isn't trusted to give me an accurate reading on a longer piece of material or on a door jam.

            ONE TOUGH LEVEL!!!
            [This review was collected as part of a promotion.] I’ve had my FATMAX LEVEL for a few years now and all I can say is, “WOW!” This tool has been dropped, kicked, drop kicked, stepped on and left in the elements! Everything from rain and snow, the cold of winter and heat of summer, this level has survived it all! Just recently I wanted to see if it was still showing level and plumb! Put it next to a new, expensive, name brand level and it matched up perfectly! OUTSTANDING TOOL!!
