This Vender (Workshop Tools) sent wrong item, Sent a lesser like item that cost $7.97 and charged me $19.99, How do I know, Vender did not bother removing sale tag marked $7.97, To add insult to in injury, Item was shipped in a damaged box, US Post office had marked box Damaged when received. Buyer Beware. I got ripped off.

I've tried a number of different stud finders in different price ranges and from different manufacturers. This one worked no better than the others, which in a word is awful. It will "identify" a stud location on one pass and give no indication over that same location on the next pass. So if you don't mind playing "guess where the stud is" and punching multiple holes in your wall you'll love this baby.

I used a friend's Zircon stud finder in February and did not like it. It gave sporadic indications, however it was their least expensive model and I don't know what kind of treatment it was subjected to before I used it (it was not new).

I bought the Straight-Line 150 LCD since it seemed to have the best overall reviews and it was in my price range. Simply stated, if you READ and FOLLOW the directions, the tool works splendidly (I am not connected in any way to the Straight-Line manufacturing company). I have only used it on drywall so I can not comment on how it works on paneling or flooring. One reviewer had a good point that if used on a rough surface, the spring-loaded contact switch on the back won't stay engaged and therefore cause it to operate intermittently. I'd suggest putting a piece of tape over the contact switch to hold it closed when working on a rough surface to eliminate that problem.

The only complaint I have is that it runs on a 9V battery. They are the least common of the standard battery types and can be a bit pricy.

I was able to find studs, but it took alot of work. Had to check over and over to get an idea of where the studs were. Glad I don't have to use this thing professionally!

Despite the high praise heaped on this stud finder by some reviewers this stud finder is not that great (some reviews must be written by the manufacturer). The directions are poorly written and the device is unreliable. I found it difficult to use and no better than others. Look elsewhere for a single purpose device.
