KAIWEETS Outlet Tester Electrical GFCI Receptacle Detector with LCD Display, 3 Prong 120V AC Voltage Socket Checker, 6 Visual Indication/Wiring Legend for Home

The pen is a little touchy on sensing. Sometimes goes off when walking around with it. I dont think I am electrified!

I used this to check out a outlet I installed. I then knew I needed a electrician.

No wires to stick in (which may limit its functionality if you want to use to test wires instead of outlets). Does 3-prong outlets only; I havent tried it with an adapter on a two-prong outlet. Can test regular outlets and GFIC outlets. So easy to read. But more than that -- it test several things: -- gives you exact volts so you can make sure its not just powered but powered correctly -- tells you if the outlet is wired correctly (e.g. polarity, neutral, hot, ground, etc) While the ones with the wires ending in metal tips might have more universal testing ability, it feels (and I think is) so much safer just to plug this in without holding on to wires. This was perfect for my needs to check outlets in my old house!

The little wand is precise enough to detect hot vs cold wires with about an inch and a half distance between the wires. Theres some bleed when the wires closer. If youre in a very tight space, youre better off with something a bit more exact. But for normal home am I about to do something dumb checking, its very good.

All indications and readings are clearly visible, but the voltage reading is not +/- 2% plus 2 counts as claimed in the specifications in the instruction sheet that came with the unit. The unit read 107 volts, while my calibrated meter read 122.0 volts

Seems to work great easy to use easy to read Will try it to see how long lasting it is

Can only be used with 120 volt outlets. Even though it will read 250 volts. Will not work with a 240 volt outlet. The blade direction only goes into a 15/20 amp 120 volt outlet. Easy to use.

The volt meter portion of the device is off by about seven volts for 120 volt power as compared to a calibrated volt meter. It works but accuracy is not good. I have an older unit with less features, but it is very accurate with the voltage reading.

This product is a quick, cheap tool for testing outlets. It does the job it sets up to do. Its not an all-purpose multimeter but for outlets its even better because it doesnt give you confusing, floating read-outs the way digital multimeters do but a hard and fast readable number and the problems with the circuit. The only downside I can say about this product is that it needs perhaps a longer reach for recessed plugs. Other than that, as a testing device it should be in every homeowners tool kit.

I like this allot. I am a novice at electrical. But with the help of some video calls to friend and this testing which wire was hot. Then using the GFI tester to make sure I did it right out me at ease.
