"So far, so good"
I've read all the negative reviews, the trick is to calibrate the device, and move slowly, with some patience it will locate the stud, even your AC line, when it says to start on another spot, do so , and calibrate again. It helps to read the instructions too, some good tips in there.

"Too advanced for it's own good"
The One Step attempted to derive an image on the display of a stud. Under ideal conditions, this would work, but ideal walls are rare. Unless you are a novice, get a simpler one with a robust signal strength meter and deep scan.

The One Step tries to produce a display of the image of a stud. This simulated "x-ray" image of studs was erratic and useless in walls that were full of more than wood studs spaced at ideal intervals covered with simple drywall. I recommend you buy a more basic model. Pipes, double studs and walls/floors covered with thick wood paneling/flooring will be problematic for the One Step Display to resolve. The human brain is superior to the One Step display driver in interpreting the content of a wall. Using a robust signal strength display on non-One Step models, as you move the scanner, the user can use his or her mind to "map" an image of the varying densities of what is behind the wall.

Perhaps Zircon was innovating too much for their own good in an effort to distinguish itself. Here the old technology is more reliable.

Get any other deep scanner with a robust signal strength display. I returned this unit and bought the Multiscanner Pro SL (similar to ASIN: B00004TRBC). For me, even the basic $20 deep scanner with LED would have been better than the One Steps.


"Re-imbursement"
This is the reason reason that I do not like
Re-imbursements.

They never send it to you.

"Doesnt Work Well"
Recognizes the existence of studs about half the time I try to use it. I can scan the same wall twice and find 2 different pattern of studs. AC mode doesnt work, it tells me their is live AC in a wall with no wiring at all. Overall, stick with hammering nails in the walls or banging on the wall to find the studs. I was thoroughly disappointed with this product.

"Love this StudSensor"
I absolutely love the MultiScanner i500. I just purchased a house and used it to hang new cabinents in the kitchen, pictures on the wall, and install curtain rods. It found the studs easily and it shined a light right on the center of the stud.

I tried using it on my mother's house and found that it wasn't working. When I called Zircon, they explained that the unit doesn't work on lathe and plaster. They suggested that I use the metal mode to find the nail head as long as the walls had only wood lathe not metal lathe or mesh. I tried that I was able to find the studs.

I haven't tried the AC mode, but everything I have tried works great. I would definately recommend this product especially to women like myself that find themselves doing home repairs.
