Query: "You get what you paid"

I just throw away my 2 existing stud finders after received and tested this Zircon i700. I also did a lot of research and forum prior made my final decision on this one.If you think buying a Zircon i700 is a waist of money...then think again, until you hit a project like I did last month trying to mount a flat screen TV on the wall. You know how heavy that flat screen TV is, so you don't want your mounting screws are off the stud's center line aren't you?I was very happy with this i700, (I talk to myself: "Ah, I finally bought something that it works!"). It helps me to find the left side, the center line and the right side of the stud easily. To be honest, 90% of the time is correct (after tested 5 times on the same spot), that's enought accurate tolerance for me. I haven't test the AC or metal yet so no comment on these modes.I'm highly recommend the Zircon i700 to everyone as I did to my brothers.
