Ordered two, one accurate, one not

I ordered two of these after reading reviews here about the inaccuracies of some of the meters. Sure enough one was correct while the other was off by half a volt which is a lot in the world of 12 volt charging.

UPDATE: After I originally posted this review, the seller contacted me and offered me a refund or a new scale to replace the defective one. I amended the review to reflect that they were incredibly responsive to my negative review of the scale.

I received the new scale today, and alas, it is the same as the first. The problems outlined in the initial review persisted. I contacted the seller and received a full refund.

I don't typically post negative reviews, as I rarely have to. I wavered between two and three stars for this scale, but decided on two, as it does not do the one thing I wanted it for, despite doing a satisfactory job with things that my other scale already does just fine.

I bake, and wanted a scale that measures down to one gram, for things like yeast and salt.  My other scale is not sensitive enough for that task, despite being great for slightly heavier, yet light weights. I bought this one because it went down to one gram.

Well, it doesn't. It goes down to 2 grams. I'd also doesn't seem to want to weigh in odd numbers, and rounds anything less than 10 grams to the nearest even number. It also seems to fluctuate a bit, by a gram or two, at higher weights. It doesn't like to settle on a reading right away, and occasionally changes.

Does it weigh smaller weights than my previous scale? Yes.

Does it do what it is advertised to do? No.

I will say that I probably should have paid more, for greater accuracy.  Had I known the problem with this scale and its limitations, i would have.

I'll probably buy another, better one, despite the fact that it might get me on a watch list.

The first one I received failed when pressure (60lb on an 80lb max sensor) was first applied.  But, Amazon took it back with no problems or cost.  The second one seems to work fine after a week of working.

One gauge is not set properly, how do I know if it's a correct reading?

I ordered two of these clocks so I would have a spare.  When they arrived only one worked.  I threw that one away because I felt it wasn't worth sending back.  The other one works just fine.

I purchase two of these and layed them side by side in a freezer overnight, There was a 5 degree difference in the readings. I wish there was an adjustment available to set to correct reading.

One battery good, the other one would not accept a charge. Returned them. Probable a fluke! Going to repurchase, but will buy one at a time to make sure I get good batteries.

I ordered two of these lights, one black and one white.  The black one worked; the white one didn't (the motion sensor feature did not work) and obviously had a loose connection inside the light, since it flickered when shaken.  Rather than deal with the hassle of a return, I ordered a 3rd light (white color) and it worked.  So overall, 2/3 worked for me.

The first one i bought was not calibrated it was off by .1 so i had a new one send out to me and works great!!!

I used this thermometer and after 2nd use, one of the probes started showing inconsistent results.  Sometimes it would show accurate temperature, and other times it would 20-40 degrees off.  After few more uses, the temperature would be consistently off, by a significant amount (see image attached, both probes are in the same location and show different temperature).  The other probe seems to work pretty well and is accurate.  Not sure how long it will last.  Other than this (pretty big deal) everything else seems to work fine.

One of the two units I ordered was marginal. I had to place a separation baffle between the transmit and receive sensor to get it to work.

Strange but true. I saw a couple of reviews that claimed they ordered two of these and one didn't work. I had the same experience. One works, but the other doesn't keep time. Boo!

I ordered 2 of these scales, one for me and another for a friend. My friend's scale works great, however the decimal place on mine is in the wrong place. It still reads correctly, it's just a little confusing at first.

I bought two of these pressure gauges. There was a 4 psi difference between the two gauges when tested. For me, this is not accurate enough.

Accuracy is more like +/-4 lbs rather than the stated +/-2 lbs.

Had ordered 2, but only received 1 when the shipment arrived.  After contacting the vendor, they promptly sent the second unit.

We had one exactly like the one we ordered that was destroyed in our move from one State to another.  We really liked the first one which was very accurate.  This one never has the correct temperature.  We have tried various windows with no luck.  If we hadn't thrown the box, etc. away we would have sent it in for an exchange.  It does keep the correct time, but we could find that by looking at a clock or watch.  The temperature was what we really wanted. We're disappointed since it doesn't work right.

I'very got one that works great and another that doesn't.  It could be the different locations. Haven't had time to do a complete comparison yet. Be careful who you buy it from.
