    1.0 out of 5 stars Non Existent Warranty - Busted after a few months
    By John J. on January 19, 2020
    I am a home inspector and use this tool many times daily. This lasted about 3 months and then the ground plug got buried into the casing and the other prongs got loose. I turned in a warranty claim to Klein for a refund or replacement and they never got back to me after 2 months. It is supposed to have a 1 year warranty. Many Klein products are good, but I see more and more complaints in recent years about Klein tools and this is another one of them. Although this is an inexpensive product, they still should stand by their word of a full year warranty against Mfg Defects. Get a Sperry. I am using this one now with good success and it has a better grip.

    5.0 out of 5 stars A Must have for homeowners and electricians.
    By Mike on August 24, 2021
    MUST HAVE for homeowners, electricians, a definite time saver!

    See first picture... Like the other no contact voltage tester too...

    I am a experienced industrial electrician 20+ years of know how... I had a intermittent electrical problem at my house... After pulling light fixtures and checking wiring this handy dandy circuit checker arrived. I started checking outlets and found a intermittent bad outside electrical receptacle that had a bad intermittent neutral connection. I would not have found this problem without this tool.. By inserting it into the socket it showed a problem (open neutral) but when I moved it around a little bit it the receptacle the open neutral went away(Intermittently working). A meter would not have found this problem without pulling many outlets this led me right to the problem.... This tool by inserting it into the receptacle showed it to be intermittent. Problem Fixed. This saved me time no doubt! This is a must have for any homeowner to diagnose electrical outlets...

    Great product. Just one suggestion. If you need both receptacle tester and non contact voltage tester buy the set instead of buying them separately. Its cheaper in Home Depot than Amazon
