it takes an extremely good contact with the probe and ground against whatever 12v power is being tested.  not reliable for that reason.

When this arrived, I was surprised at how heavy it was.  It's very well built in terms of the connectors and the overall thickness of the shielding.

But the big gain for me with this heavy duty cord was in the performance and safety of my leaf blower, compared to the cheapo cord I was using. With the old cord, the blower motor sounded a little off and when I measured the voltage with a meter,  there was a huge voltage drop.  This could damage appliances, , but more importantly, it's very bad news from a fire safety standpoint.  Low voltage from undersized extension cords is a major cause of electrical fires.

With this heavier 12-gauge cord, the voltage stayed at a safe level and the leaf blower motor sounded much happier.  If you're powering high-draw appliances with an undersized cord, do yourself a favor and buy this extension cord!

It grounds and has a lot of area. I like the concept better than the bracelets. I mean it occurs to me that if I'm to be afraid of my electricity I might as well be afraid of other forms of electricity. If I'm going to protect my stuff, I think it's preferable to have a device that protects it even when I'm not there. That it did; my mobo, ram and processor are all working fine. Hence a four star review.

Appearance: It doesn't look cheap, and I wouldn't feel embarrassed to pull it out. You may want to see if you can find one of those plastic poster tubes to cart it around as the packaging is square and less manageable on your person that a round storage device. However, the packaging is solidly built cardboard.

Ease of use: I don't think ASDs (anti static devices) are easy to use at all but this one gets extra points due to the fact that it doesn't chain me to anything. I honestly think grounding is way more a chore than most people let on. Finding a verifiable ground that is within reach of your workspace and able to clamped on to can actually be quite hairy, especially in a domestic setting. What I did was ground the case with a powered off power strip and then clamp the pad to the case so I could work with it. I would only give it four stars if it made the whole procedure into a matter of plug n' work. For five stars, I would need it to come with a warranty that protects everything I use it on and for it to make me a sandwich, a good sandwich. Five stars is perfection after all.

Portability: Read the measurements, it's 19 inches, this is quite obviously less portable than a bracelet. It's in fact the least portable ASD solution marketed as such. It is more portable than a DDr (Dance Dance Revolution) pad but it not interactive with any gaming consoles I know of and therefore can not be used to play video games. It''s more compact than a full sized tower with a power strip, but those are really not marketed as Anti static devices.

All in all, good product.

I was looking for an extension cord with the flexibility of using a different power source other than the cigarette lighter.  I didn't need the alligator clips, so I didn't need to worry about if they were soldered on wrong.  I just cut them off and used my voltage meter to verify the polarity in my application.  I would double-check if you do plan on using the alligator clips.

The gauge of the wire is more than adequate for my application. They are of a heavy gauge which should be adequate for power-hungry devices connected up without the worry of overheating and the possibility of catching fire.

Both the male and female ends make good contact with their mate.  Some of you know that if the connection is loose, it can create a 'hot spot' and get very warm.

I am very pleased with this purchase.  It was reasonably priced.  Please double-check the alligator ends for correct polarity.  It could have already been corrected in-house.

Almost everything I hear about this is true: It fits very snugly, its profile is low and eye-pleasing, and it charges devices well.

The only thing that turns out not to be true is that if your 12-volt outlet has a cover, the cover can close over this charger. I've tried it in both my cars on covers that seemed pretty ordinary, and the covers will not close with this charger in place.

It's your call whether that's a deal-breaker or not. I endorse the product for performing its main function exactly as advertised. I even bought a second one a few weeks later.

This turned out to be more rugged than I expected.  It makes sure that my S1100 doesn't get smacked around inside my computer bag, and has a little separate compartment or channel for storing the connecting cord.  Once or twice before getting this, I'd get the scanner out only to find I'd left the cord at home.  I also got a very compact self-coiling USB cord, and leave the longer OEM micro USB cord on my desk, so now I've got a fallback in case I lose a cord while out and about.  There are even a little flap to connect the cord through without removing the scanner from the case.  The front and back walls fold down to allow full functionality of the scanner.  Surprisingly ingenious design.

Very good wireand high-quality insulation. Definitely 12gauge.

This is a great grounding probe for a saltwater aquarium.  It works well and has an extra-long cord making it easy to place the probe in your tank secured with the included suction cup mount.

When used with GFCI power source, a grounding probe can save your life if lights or a heater short circuits in your tank.  How much is that protection worth to you?

WARNING: Must be used with a GFCI outlet/breaker!  Dangerous to use alone.

A little bit small, but very good heat isolation and very good outlet design.

just like the other reviewers it is a good piece of test equipment for 12VDC systems.

I was playing my electric guitar in my basement a couple months ago when I felt a mild tingle in my hands. After reading up and considering getting my amplifier repaired, I decided to spend a few bucks on a tester first. I found out that despite having three prongs, none of the outlets in the basement are grounded. If I knew that before I bought the house, I would have made the seller fix it.

This tester works great, is easy to read, and is very inexpensive.

For the price you cant beat it.  Probe and controller feel high quality.

I was surprised and impressed with how well this little thing works. It charges fairly rapidly and gets a good ling flight.
It's very rugged as well. I've crashed countless times and still have not broken a prop. The flight secret is to make sure and trim it out before flying. You know it's trimmed when it lifts straight up when it launches. I'm going to buy another one for sure.

So far it's working well and nice not to have a power strip on the ground.  Had to play with it a little get it settled in the right place so that the light came on saying the grounding was good, but it's been holding so far.

I've been using this switch for over four years now, and it's simply bullet proof. It incorporates some really smart electronics to anticipate and alert the user about potential pump problems, like over current, short cycling, etc. It learns how long it should run to optimally drain any pit without running the pump dry, and it auto calibrates on a regular basis. Smart. No floats to get stuck, no unreliable pressure switches.

After a power outage during a storm last year, I added a battery/inverter to my pump, and I found that when running on inverter power, the switch acted a little weird. I contacted the manufacturer and they told me that they had identified this problem and modified later units to fix this problem. I sent it to them and they updated the switch and replaced the sensor with the new style, all at no charge. Doesn't get any better than that!

High quality pointer that operates on a single 9-volt battery.  Pointer is very specific and responsive to metal objects.  It is an essential piece of equipment once a plug of earth is removed to isolate the item to a specific location within the dirt plug.  Also has a nice single LED light to illuminate the earth which is great in low light conditions.  This model is also water resistant which is a nice bonus.  Comes with a belt holster making it easily accessible when needed.

I like this very much.  Except occasionally the outdoor remote sensor stops transmitting to the base unite.  Cycling the remote's battery eventually establishes reconnection.
