Question: how to measure ac circuits
Document: just to let everyone know Sperry did honor their warrenty.They replaced my broken tester just had to pay to send my unit to them.My only complaint after all this is that the process of sending it back to Sperry, them checking it to let me know if they would cover it and then sending me a new unit took almost 2 months.......Would have given them 5 stars if their process was faster
Wife loves this product. Changed out all our switches with no accidents. Necessary for checking for hot wires--works great!
Very good for the price, I use this nearly everyday at work and have on had one problem. It you drop it several dozen times as I have you'll end up having to replace the screw that holds the battery tray shut as it's plastic and breaks pretty easy.
Answer: no
