Stud Sensor Detector Edge-Finding Stud Finder with Sound Warning for Wood,Metal ,Wall Studs,AC Wire Detector with One 9V Battery Included

It's a very average product. It has issues detecting studs; it's a hit or miss. Sometimes it works and sometimes it doesn't; and unfortunately most of the time reading is false. Long story short; take your money elsewhere and buy a better product.

It works OK. It does seem to have trouble discerning a fire block from a stud.

Worked but not always properly

Can't fully rely on its reading.

Couldn't find the stud :(

Works well, Little too sensitive in older houses. Horse hair plaster with slats are solid and it can't see the physical studs

Nothing fancy. Actually took me longer to find stud since this is incredibly inaccurate

Does not work I used it on wall and marked where it said studs where and missed them every time do not but save your money knocking on walls is more precise than this is
