## Customer Reviews

### ⭐⭐⭐⭐⭐ Simple to Use - Not Too Expensive
*by N***. on August 8, 2025*

I purchased this based on a YT review. No issues, no complaints, no second thoughts. I've never owned one of these, so I went with the slightly cheaper version. Works great. One of those tools you don't use all the time, but very nice to have when you need it.

### ⭐⭐⭐⭐⭐ Favorite plug tester.
*by T***Y on September 25, 2025*

My favorite plug tester. It has the gfi test buttons, it’s small and reads pretty easy. I’ve tried other Klein versions (had the big LCD screen one, but too bulky!), the fluke (also too bulky for me), the harbor freight one seems to be modeled after this one, the Milwaukee one (also too big IMO)

### ⭐⭐⭐⭐⭐ 100 % as described no issues
*by B***B on September 4, 2025*

Without a doubt worth the money works to a T and gives you exact wire configurations that are incorrect
