Bests & Worsts Reviews from Amazon

The videos are very misleading! They never show the effort needed to calibrate the device (anytime it losses contact with the wall). You must hold a button on your phone, while making large consecutive circles. When it is finally callibrated, you must use a "raw" sensitivity setting that shows everything like a blobish weather map. Once you've zoned in on the right sensitivity. you switch to the simulated mode which makes certain blobs look like a stud, and other blobs look like pipes. They are not real pictures of whats behind your walls. AND, all this, without letting the phone leave the wall. If the phone comes off from contact with the wall, you must recalibrate. Then, the instructions say not to trust the image, but to drill pilot holes before drilling, really, what is the point then? Product fail. Thankfully, i was able to return mine to Amazon for a full refund. I give Amazon 5 stars, but Walbot gets only 1.
