You can ignore the seemingly low review rating on Home Depot. Turns out it is only 3 reviews, 2 5-star and 1 1-star from an idiot who didn't receive it and thus dinged the product. People who rate a product based on the delivery deserve a special place in hell.

Order from HD for the extra 10% military discount.

Can anyone help me to explain what is the difference between this posted tester vs a normal/conventional one? Is this only for GFCI socket? I thought the normal one can use for GFCI socket as well

When you press the GFCI button on this one, it will cause a small internal ground fault, so you can test if the GFCI is working.

Amazon link didn't work for me either the first time, after a few minutes I tried again and it worked. I think the problem is on Amazon's end.

I get that its only $2 more, but what value does the brand name offer over a random chinese one given that outlet testers are so simple electronically?

Or for that matter, one of these that provides more information (make sure to select US plug and spend $10 for free shipping):

GB is a legitimate brand. I have a couple of their tools. When you spend money on tools for working with electric you don't want to cheap out since electricity can kill, cause fires or damage whatever is powered by electric.

I was looking for a tester this morning and bought it for $8. I already have it! Tested it out and it works. It's a little bulky as you can see. But it sticks out fine enough and works. And it's Fluke! I'm happy with it.

In general I wouldn't get something like these given the nature of wanting them to be accurate every single time. I'll go with a reputable company for things like this.

I actually prefer the other format - but have the Fluke in my tool box now - the only reason I have the Fluke is because mine came with the Non Contact Voltage tester and a circuit tracer (see which breaker to flip).

The other format of plug fits anywhere ... the Fluke one is bigger/clunkier when you are trying to plug in behind a sink or what have you.

Fluke branding carries big respect and GFCI is a potentially life-saving safety feature. Hypothetically, if this device lies to me and says a gfci is good when it isn't, fluke having some liability makes me feel better than "oh yeah i got that tester from aliexpress".

Does this Fluke, or other units, detect ground wired to neutral?

This is known as a 'bootleg ground'. I just came across this, and learned about it, when working on my mom's old house. It had originally been a 2-prong outlet house, but during some remodel in the 70s all the wiring and outlets had been replaced with 3-prong outlets.
However.... not all the wiring had been replaced... the far side of the house only had hot/neutral wires running to outlets and were 'bootleg' wired.

my klein and old sperry brand outlet tester both said "correct'
As a result, what was supposed to be a single outlet replacement ended up in opening all the outlets in the house and checking wiring on each one. I found a total of 3 outlets done this way, all on same circuit. Ended up replacing the one outlet, running a new 14/2 wire in place of the 2-wire (90% under house in crawlspace fortunately.

and I first checked the breaker panel... it was all 14/2 or 12/2 wires... but was spliced to a 2-wire only in crawlspace in a junction box!.. so freaking odd.
