Review on VIVREAL 4 In 1 Stud Finder Sensor Wall Scanner - LCD Display, Sound Warning & Auto Calibration For Wood AC Wire Metal Detection by Eddie Kittylovin

Bought this primarily for a stud finder to replace and old one. I will give a review of all the features.This item was easy to use, however it is important to remember to go slow.This review is in hopes you already know to put it against the wall or whatever structure you are using it on.First, appearance. Nothing special, decent screen, lights up when you press the button, easy to read.To use: When you press the button you have to wait about 1-2 seconds. You will see a full bar on the screen that will drop and then beep. You are now ready to go.Stud finder: To test this before putting unnecessary holes in the wall I attached a 2x4 to a 1/2 inch plywood to test it. It found the 2x4 every time both horizontal and vertical. I then tried it on a drywall where I knew where the studs were. Found them every time. I then went to the wall I need to find the studs. It worked flawless, no extra holes. The stud setting also has a symbol that tells you if there are electrical current behind the wall. I tested it around electrical plugs and switches. Every time I got close to them the electrical indicator came on. Pretty good safety feature. Note: I have metal studs in my house and the stud setting found them with no issues.Deep scan: This seemed to function with no issues as well. Tried it and it picked up items about 1-2 inches from the surface.Metal: This also seemed to find metal in the wall. I didn't tear the wall apart to see what it actually found.AC: This is good if you have unattached wires and want to determine if they are live. I tries it around a socket and switch. As I was moving it around each one nothing. As soon as I put it over them it alerted me there was live power.Overall I thing this is a very good product that seems to function as advertised. I did drop it onto a concrete floor, by accident, it just bounced once and that was it. It still worked fine and there were no noticeable damage.I would recommend this item as it worked flawlessly for me every time I used it. Just remember to go slow and you should have no issues.
