Review on VIVREAL 4 In 1 Stud Finder Wall Scanner With LCD Display - Center Finding Beam Finder And Sound Warning For Wood, AC Wire, And Metal Studs (Black/Silver) by Jeremy Lunn

Updated 10/21: Adding one star for fast customer service email offering me a full refund. I have returned the item a long time ago and received the refund from ebay so I don't need their offer. But a refund policy like this is worth adding one more star.Ok it works fine in general if it's inside the house. The reason I returned it is because it really does not do anything better than the old one I bought 20 years ago. I intended to use it for finding a stucco wall stud and it can barely find the stud (just like the old one).
