Does this thing actually work? My old Fluke gave up the ghost and Iāve bought half a dozen different models/brands trying to replace it. So far, I wouldnāt trust my emenies life with those things. If I get this and get electromacuted, can I come back as a ghost and sue Woot?
The TL;DR Version
See below for the bottom line, like itās literally the bottom line. You canāt miss it. 
For $10 itās probably worth it, especially if you have free shipping with Prime. I have two āgo toā meters that I keep on hand. My first is obviously a Fluke, itās a model 107 that I got cheap and works just fine, but I needed more features for electronics projects and picked-up the Kaiweets HT118A back in June for $30 and the thing is a beast! I ended up liking the thing more than I thought I would. The last time I had to āgrab a meterā for something, I grabbed the Kaiweets primarily because it wonāt cost another $100 to replace if it failed ā and it didnāt ā once again I was quite satisfied with the purchase. I ended-up getting some of their cables, probes, and the like and was also very pleased with the level of detail they put into their product. It frankly didnāt suck. My HT118A does have a built-in Voltage Tester and I would think itās from the same factory or at the very least a similar design. I move it close to a āhotā wire and it beeps. I take it 6 or so inches away and it shuts back up. The only recent meter that I had a problem with was an Amazon Commercial and it literally lasted a day. Granted I was working with high current, but it was within specs and it blew in under a second. I figured it looked nice and had features galore, however I opted to buy the Kaiweets above instead of exchanging it. Iām sure if it was less current it would have been fine, but thatās not a good sign on āday one.ā
The Bottom Line
I havenāt used this particular tester, but if it was me Iād grab it ASAP before it sells out as Iāve had nothing but good luck with the brand! 
I do, and I too, also have a Fluke (I think I bought it here on Woot) but your informative, descriptive and thorough review of your similar pen tester convinced me to get one of these.
Thanks.
Just pointing out @SuperFlyEDSguy 's thorough description was for a full multimeter, not a similar pen tester. They are using that one item as proof of quality of all products within the brand.
I can live with that. Iād better because itās past the 2 hour order cancellation window. ha ha
I donāt know about present-day but back in the olden days one could rely on certain product lines or brands.
Since I already have the Fluke, I think this pen tester will compliment it nicely. I wouldnāt have ordered another full multimeter anyway.
Can this tester tell the difference between ārealā voltage and āphantomā voltage? By phantom, I mean a voltage induced in a nearby wire that disappears if any load is put on it. My current tester screams when it detects either which is annoying when the wire is actually disconnected at the circuit breaker but picks up a voltage from another nearby wire and sets off the alarm even though it canāt zap me.
lolā¦ I read all of it anyway. Iām neurotic that way 
I went ahead and got this. Remembered I had a TTHH coupon so it was free! YAY!
All of my multimeters are Fluke as well - well made workhorses - but I use these no contact pen testers just to make sure that thereās no voltage when Iām working with wiring. I donāt trust turning off breakers. Iām neurotic that way too! Iāve been hit with enough high voltage in my life, I donāt need another charge. lol
Thanks for the VERY detailed reply! Hopefully thisāll work better than the others Iāve boughtā¦
A pen tester that gives compliments?! For $10, Iām all over that ā¦
I trust the meter, but in one of the pictures, not sure Iād trust the gloves handling live circuits.
Are these safe?
$15 on Amazon, not the $30 claimed, so not that much of a deal.
Everybody knows that you need OveGloves for working with line voltage!
Yeah, Woot and Amazon both like to quote āmsrpā as the original cost, even if it never sold for that, so that they can claim that youāre getting a fantastic deal shopping with them. I never take that into account. I just look and see what similar items actually go for.
List Price = MSRP <> Amazon/retail price
Thanks for pointing that out, but I did make mention of my two subsequent orders for the Kaiweets accessories. The probes were of very high quality, so I obviously wanted more along with some of their other wire kits. Lots of overall items, and none disappointed.
Some Thoughts on Brands & Quality (TL;DR)
Youāre obviously correct that back in the day brand names meant so much more than they do today, but something Iāve noticed more-and-more recently is the number of different brands, some even competing, that are all buying from the same factories in China ā and itās not limited to the no-namers, but rather big tool manufacturers included ā there are varying levels of quality for groups of similar items, but the reviews are shockingly similar across the board!
Provided they are manufactured at the same factory; generally the comparable entry, prosumer, and professional level products will all be roughly the same quality regardless of brand.
Now hereās where it gets really interestingā¦
Interestingly enough Kaiweets is doing it too, which is not surprising. It would take too long to look up the individual products, but a quick search of Amazon for āLarge LCD Multimeterā brings up AstroAIās version of Kaiweetsā brand new 10,000 count meter, and BOTH of them have the same 4.6 out of 5 star review!
Returning to tools, I started to notice quite a few items by SATA lately on both Woot and Amazon, so I looked into them and SATA is an Apex Tool Group brand. Apex owns some names that most of us will never see, but they own Allen ā the original HEX key, they also own Crescent, GearWrench, K-D, Lufkin, Plumb, Weller, Wire-wrap, and Xcelite. Apex is not very big in the mainstream power tool space, which is surprising being an ~$1.6B company! Whatās not surprising is that I jumped on those SATA deals and for the most part loved the quality of the products I was sent. I purchased two of their 62 Piece Mechanics Tool Sets, which I knew were entry level and expected entry level items as one was for the kitchen for everyone to grab a tool kit for around the house and the other was for my 10-year-old son since he likes to take tools for everything and never put them back! Now the more expensive tools looked respectable, which is how it should be, but even with the tool sets I just mentioned nothing really sucked and it was well worth the money!
My Final Thoughts 
My point being that all these companies are buying from the same exact factory thatās likely in Shenzhen or Ningbo, just with slight variations that are slapped on depending on the volume of their request. Either way, a $10 tester with free shipping is virtually a throw away item. I would likely buy two if I needed one myself, just to have the spare.
Wow! A great many thanks on the kind words, 
but as @Ed3rd mentioned I do have the Kaiweets multimeter with the voltage tester built-in. I sent over a quite detailed reply to that mention as I have some importing experience and am very familiar to how these dealers operate. The bottom line is that if I needed the smaller tester, they have already proven themselves to me with a full-size meter that IMHO is better than my Fluke 107 in many ways. Just to recap those thoughts, I would buy the pen tester in a heartbeat because itās either (a) similar design, and/or (b) build in the same exact factory likely in Shenzhen. This is one of their best sellers with 4.5 of 5 stars! As a $10 purchase I would personally buy a second because Iām weird like that, but I already have plenty of electrical and electronic testing equipment, which is the only reason I passed on this deal! 
Enjoy your new tester!
Many thanks for the very kind words!
Whatās a TTHH coupon? I never heard of that one.
Speaking of which, I have a crapload of Discover Cash Back Points that I could apply instantly to purchases on Amazon, but I am seriously saving those although itās kinda very hard to resist free product!
BTW, though I have Flukes, I have this weird affinity towards trying new gear and thatās how I ended up trying a Kaiweets multimeter in the first place. Going back to the 90s I was a Navy Electrician, so I am trained to be allergic to getting shocked! 
I cracked myself up, which means I am too tired! 
My point is that I totally agree that you must heavily respect electricity. I have only been shocked once as an adult (the kid story is TL;DR, but letās just say it was kids having fun, alright) and it was low voltage, sorta. I was checking a phone jack at home or adding one, donāt remember as it was also in the 90s and being used to working on 440V and even 4,160V, I incorrectly assumed that I wouldnāt get a shockā¦ and then the phone rang! 
So, looking at 48VDC + the burst of ~90VAC RMS @ 20Hz, I was thrown back about six feet! I learned my lesson that day and have since always checked that phones were disconnected before working on them! 
#TheMoreYouKnow
Best of luck with your new meter!
I think youāll be just fine, besides $10 was a steal!
heh heh.
I have no wordsā¦please do allow me to express myself in video form:
*a plethora.
TTHH is āThunder Things Happy Hourā. @ThunderThighs is the Woot Goddess who rules this place and every so often she does a āHappy Hourā where we all sit around naked, get drunk and talk shit. Waitā¦ whatā¦ you mean the naked part is just me!? Oh wellā¦ anyway, she gives out coupons to us lowly peasants for $10 off purchases. Using that, I got this for free! Canāt go wrong with free!
Iāve been doing electronics since I was old enough to hold a soldering iron. Once, I had a job a thrift store doing their appliance and electronic repairs. My dumb ass went to cut a power cord off a defective toaster ā¦ with a pair of metal scissors ā¦ and forgot to unplug it first, Not to be out done by myself, while working on one of those old rear projection tvs (it was modern then) I thought itād be a good idea to tough the high voltage anode while the set was running. 30000 volts will wake you up real quick. These days, itās just ignition coils, but those little suckersāll bite too!
lol
