The Black + Decker Bullseye is a simple tool, but it does have a few great features that help with many projects that require a stud finder. First, the name comes from the large circle on top where there's a hole just big enough for a pencil tip to mark the wall, ensuring accurate marks every time. There's also a wire detection feature in the form of a small red light. Where it really shines, though, is the laser level. We found this feature to be super helpful when hanging multiple picture frames, allowing us to line up nails and hangers with precision across a room. The laser is broad enough to work on textured sheetrock as well, which not every laser level is. 
We didn't love how bulky the Black + Decker tool is, as it makes it a bit cumbersome to use. It also isn't the most sensitive sensor, forcing us to drag it across the wall slower than some of the other models we tested. Still, it was our favorite for hanging a bunch of picture frames, and we'd recommend it if you want a level and a stud finder in one tool.

Made from CNC cut solid aluminum, the Ideal 35-207 6" Electrician Level earns our top overall spot for its versatility and durability. The packaging includes two durable acrylic vials that are easy to replace with an Allen wrench in case of breakage. The conduit thumb screw was very easy to use, and we especially liked that the magnets were embedded on a grooved rail so that it snugly adhered to pipe materials. Its versatility is appealing, boasting five levels: a bull's eye, horizontal, vertical, 30, and 45 degrees. This little level is one of the smallest in our test group and has easy-to-read bubbles with a slow viscosity, which we preferred over more watery competitors. Although the vials were smaller than others, the color contrast with the aluminum frame and neon-colored liquid made for easy reading, even in low light. We appreciated that the zero mark on the ruler coincided with the edge of the ruler, allowing the user to measure in a corner or against a surface without a gap. Though it may seem obvious, only the Ideal and the Milwaukee shared this feature. Most levels had the zero mark set back as much as 1⅝ inch from the edge of the level. The one-handed, grooved thumb screw mates well onto conduit and piping, holding fast at all angles. 
Other than the price, there isn't much to complain about. We feel that all of its well-thought-out attributes make it worth the higher price tag. If you are an electrician, plumber, or professional of any kind, this is a great product to keep in your back pocket or tool belt.
