James Arnold I’ve used it since they first came out. I’ve never had any problems with it. I’ve recommended it to many others.

Sullz McGinnis I bought this meter as it was recommended by Charles Buell.  Thanks to Charles, as I couldn’t have made a better choice. I value his  mentorship. 

David Clay I have the Extech. I don’t recommend it. Beeps constantly turning on off in a pocket or tool pouch and pins become loose a lot. It works great, but it annoys me…

Anthony Wharton I’ve had the Extech for two years now. Works great!

  1. I own the Protimeter BLD5765 Aquant non-invasive version of this moisture meter. It was about $194 cheaper than this one. However, I miss my old basic yellow colored pin type GE Protimeter BLD2000 Mini moisture meter. That lasted about 12 years before I lost it.
