Amazon would need to introduce a system of negative star ratings in order for me to adequately express how miserable a read this book was.

I like this unit as I use it for my business as a home inspector however the sticker that's on the top which is a key for the lights and tells you what's incorrect about the outlet comes off after a while of use.

I installed product without a problem but could not properly register the product online after many tries. Online text help did not address this problem. I tried to speak to a customer service rep on two occasions but an over an hour wait time was indicated both times. A hopeless situation.
