I could not get it to work. I'd find "pipes" in the wall. Let's say one was oriented vertically. As I moved the thing upward, the "pipe" appeared to rotate inside the wall. I could not figure out what I was looking at.
But let's assume that if I move it smoothly across the wall, it will work: the walls in my place are sixty years old and are not the dead flat smooth wall you get with modern drywall. The Walabot kept grabbing at the wall, so it was very difficult to move across the wall smoothly. I could not get the same image twice, and the image coming from the other side was not simply some reversed analog of what I saw before.
During the time when I was trying to make it work (December 2016), I needed a working stud sensor (that's not a compliment right there!) so I bought a Zircon HD55 Stud Sensor.
On the Zircon, the part that glides across the wall appears to be velcro loops, which don't grab. The velcro loops are near the top and the bottom of the surface and contact the wall vertically over a span of about 1 3/4". The surface of the Walabot that is supposed to glide across the wall is a dead flat matte finish plastic that goes the entire height of the unit, about 5 1/2".
The only reservation I have about saying the Walabot is worthless is that the unit I have, a Walabot DIY, has only two antennas (IIRC), but there are Walabot models with up to five antennas, again, if I remember correctly. It's a pity that the unit that might work GREAT, the five antenna one, is priced much higher than the one suggested for the DIYer, but the DIYer is exactly the person who would need the better unit!
