Reviews

"Finally a tool that actually speaks my language. Asked about derating for conduit fill and got the exact answer with the code reference. This is now on every phone on my crew."
"The Spanish toggle is huge for my guys. Half my crew is more comfortable in Spanish and now they can look up code themselves. Worth every penny."
"Used the box fill calculator three times today on a commercial job. Saved me from having to call the office. This thing pays for itself in one day."
