I'm in safety by trade and wanted a simple GFCI/Live wire tester for my daily use.

This is definitely a cheaper kit but I think for the cost it's great for a weekend warrior or someone who won't be using this every day.

Overall I'm happy with the quality and I think the price is reflective of its quality. Nothing exceptionally bad or good about it. Just a barebones kit.

Non-contact tester is dangerous

The stick tester is not trustworthy. It has gone off when the breaker has been off and not gone off when a wire was hot. If you rub it fast enough on your arm it will go off. If you're using it to get an idea then it's great but if you are trusting your well being on it, don't.

Good quality electrical voltage testers. I really like the plug in tester and it has a test feature to trip / test GFCI outlets.
The no touch wand is good but I trust my multimeter more to check line voltage.
These are very handy and convenient tools any homeowner could learn to use quickly.
Note: these tools DO NOT GUARANTEE YOUR SAFETY. THEY PROVIDE A WORKING GUIDELINE FOR ELECTRICAL REPAIR.

The media could not be loaded.

The non-contact voltage tester is a pretty cool little device. I have noticed that it won't do anything for battery-operated devices - but then I didn't really expect it to. Just putting this here for those of us who don't know any better... Even with a powered device like a cell phone charging by USB port from a computer it gives no indications. The functions it has are great. When a battery is installed it is ready to go, and doesn't need anything else but a user to hit the button continuously. The tester will give a little test beep and a flash of the indicator light each time you press the button. The button has a nice tactile click as you press it, and as you release it. As you near a device that has supplied wired power to it, it gives a continuous audible tone and the light stays on. It has a good mold pattern, and very good grip surface, with textures areas. The pen also has a nice handy little pocket clip. This device does not appear to be water resistant, because it has an open pathway to a speaker-output. Do not get it wet. The model I received with this pack was the GVD-3504.

Next we'll move to the other device - The GFI-3501 GFCI Outlet Tester:
Unfortunately, I don't have any GFCI devices in my home to test this with. But, I was able to try and use it on several outlets in my home. I even tried it on an outlet in a back room that I was fairly-sure had blown in the past, because I remember an arc-flash coming out of it at one point in time and black soot on the outside of the cover, but never used it after that. This tester confirmed that it seemed to be okay and in working order. Now I won't have any reservations about trying to use it again. There are 3 tinted covers for lights on the front of the device, 2 orange and 1 red. The device has a 3-prong US plug on it, and appears to be solid (no cuts or seams on the grounding plug) and not simply bent sheet steel as you see on some cheaper appliances and devices. In the middle of the device there's a nice inward slope, with 4 ridges, for easy grabbing, pulling, and pushing of the device. This really helps with pulling it in and out of stubbornly tight sockets. On both sides of the device there is a reference sheet to what the indicated lights means, and is very helpful to not have to carry around a paper manual that would get destroyed within a week's time with daily use by some trademen. The device seems to be of decent quality, and I look forward to using it more in the future.

Ultimamente he estado realizando algunas instalaciones en mi casa, agregando dimmers, agregando nuevas tomas de corriente, haciendo la instalación electríca de la casa que tengo en construcción. En mi casa tengo multimetro con el cual checaba neutro, línea y tierra para la verificación de la instalación. Pero con este tester es muy sencillo detectar la línea sin contacto. El verificador de tomacorrientes funciona tal y como lo esperaba, tiene todo para que verifiques que tus tomacorrientes están correctamente instalados (tierra, neutral, línea, invertidos).
Un excelente producto a un bajo costo.
