Great gadget
This wall stud finder is simple and effective. It accurately detects studs in walls, making hanging shelves or pictures much easier. Lightweight and easy to use, with a clear display. Perfect for DIY projects around the house, though not as advanced as some higher-end models.

Very useful
Bough a different version of a stud detector that was useless and was sent straight back, after seeing a short video of this on Facebook I thought I’d give it a try, opted for this model although there is a slightly larger and more advanced model this was all I needed and it performs as promised as I need to put some cupboards and shelves up and don’t want holes all over the place. Spot on would highly recommend

Great stud finder
I have had multiple stud finders over the years but I can honestly say this is the best even though it gives some false readings. I would definitely recommend

Excellent Piece Of Kit.
This is the best one I've ever had and there's so many functions on it you can track your wall easily. Bought another one for my son when he moved to his turnkey semi detached house. Brilliant!

The Stevie Wonder of wall finders
Terrible product, the stevie wonder of wall finders. Lights turned on for no reason causing multiple unnecessary holes.

Very accurate and easy to use
The most accurate stud finder I have used and I have used many different types. The LEDs light up red to show the width of the stud and when the centre of the unit is in the centre of the stud, a green LED lights up in the middle. There is no calibration against the wall required. Just hold the button and go. I've found of the unit has trouble finding a stud or is giving a random pattern, it is 99% because there are random studs in the wall.

Best stud finder I've ever used
This is the absolute best stud finder I've ever used. I've had terrible experiences with rubbish ones that can't find anything but this is outstanding. Superb at finding studs and really accurate, no messing about guessing. Life saver.

Slightly better than a stab in the dark
Unreliable, only slightly better than a stab in the dark, mostly due to random false reporting, you need to plot out across a large area, and then make an informed guess. Tried changed batteries for different brands and new, to no avail. Our walls are plasterboard with a very thin plaster coat, mostly ¾ of an inch. Overall it’s a very disporting purchase.

This stud finder is incredibly user-friendly, even for first timers and DIYers. It’s fast, simple to operate, and gives reliable readings without any guesswork. The quick and quiet operation makes it easy to use without being disruptive. It also feels durable and well made, which gives confidence it’ll last through many projects. A great tool to have on hand; straightforward, dependable, and gets the job done.

The Franklin Sensors ProSensor M90 Stud Finder is hands down one of the best tools I’ve ever purchased for home projects! With its 9 sensors, it provides incredibly accurate and precise readings when detecting both wood and metal studs. I used it to mount shelves and hang pictures, and it worked like a charm every time. The light bar shows you exactly where the stud is, making it easy to find and mark the perfect spot. What I love most about this stud finder is how quick and simple it is to use. You don’t have to worry about calibrating it or making multiple passes—just run it across the wall, and it instantly detects the studs. It also works great on both drywall and plaster walls, so I don’t have to worry about switching between tools for different surfaces. The Made in the USA quality gives me confidence in its durability and performance. It feels solid and well-built, and the ergonomic design makes it comfortable to hold and easy to maneuver. If you're looking for a reliable, easy-to-use stud finder that gets the job done right the first time, I highly recommend the ProSensor M90. It’s a game-changer for anyone working on home improvement projects.

Have used this a few times now & it is great at identifying exact location of studs. It got a little confused one time (all lights illuminating across the wall). However, when used on the opposite side of wall it worked perfectly - so maybe there was something setting it off. Overall very pleased & would recommend over cheaper less accurate items.

This is simply the best stud finder on market. Very precise, I had never missed the stud with this device. Also very easy to use.
