Not only is it awesomely priced, but it's extremely easy to use. I'm not a builder or contractor by any means, however the instructions it comes with are very clear and easy to follow. The Lifetime Limited Warranty is definitely a plus!

Simple easy to use. Thought it should have used AA batteries but I guess AAA will work

Great tool for securing items into studs. Will give you electrical warning and help you determine the center of studs. Have you used it on many projects successfully.

It works so good I threw my other stud finder away.

This is a great tool! It’s so easy to use, you can find studs using one hand. Great for checking for ceiling joists.

I have owned numerous stud sensors over the years, but the Sapphire 9000 is by far the best I've ever used. No more guess work - the Sapphire 9000 indicates the middle of the stud as wee as the left and right edges of the stud. Fantastic - I'm really impressed!!

This is a great product but sometimes it gives a false alarm not sure whats the issue.

When used over cultured marble in the shower readouts very as to whether or not a stud was found.

It works really well

Pros: Easier to identify the center of a stud. Cons: It seems to vary +/- a ¼ inch passing over the same stud multiple times.
