One of the reasons I'd like to get this working is that the "car" remote for this unit doesn't work more than 2 feet from the unit.

The best of them are comparable to the ones made by Peak/ Atlas etc., - at least in design if nothing else - the rest are pretty much hopeless. But because there's no reliable branding and no reliable IP law in China to protect more reputable manufacturers, you can't tell what you're getting; if it's any good at all and how long it's going to last.

It was just the circuit board and I had to put it in a case. I have compaired the components it tested against some known value of components to verify them.   I bet if you open the Peak one it will have a lot of Tiwan or other such parts in it. There is some junk comming out of China,but some very good stuff also. Isn't lots of the Apple stuff from China ?   I have bought some volt meter boards from China and they are right on with my Fluke meter. These are not multimeters, but such things a a 3 digit circuit board that you have to put in a case. Even the one I use to monitor the 120 volt AC in my house is right on and has been working over a year.

Dunno about the Chinese stuff.   I hate to break it to you, but the peak tester is the same as the $ 15 to $ 25 Chinese tester but put in a box. Peak also rips you off as the ones from china combine the resistor/capacitor/inductors with the transistor/simiconductor test. The ones I see advertised form Peak have seperate units.         Er, let's get this straight then, so the Peak is NOT actually the same as the Chinese one which apparently does other things as well?         I have one that was just the circuit board without the case. Put it in a box myself. It usualy works very well. It will sometimes get confused on some parts. Some transistors will read funny, but if you change the leads around they will read correctly. That is all in some documments I found on the internet about them.       Er, let's get this straight again then, so the Chinese one you put in a box and you think is the same as the Peak, but obviously isn't because it does different things, apparently doesn't even work properly?       You're having a laugh, surely.     Gareth.

The way the software is written there are sometimes false indications. On some transistors that have lots of leakage it may depend on which lead is connected . If a transistor reads bad or the results are very much differant than what they should be, try changing the leads around.   What I say Peak is a ripoff is that the software that is written for the testers can have it all, but Peak makes two versiong so they can double the money.   Over the years I have seen many devices where the main circuit bord is the same and differant names put on them. My wife worked in a cotton mill at one time. They had some nice boxes they packaged towels in and sold for a high price. Put the same towels in a large stack without the box and they are less than half the price. My dad worked at a place that made brake shoes. They had several brand names put on them. Sometimes that if a big order came in they would sand off the name on some of them and put the name of the rush order comapny on them.   The whole deal is that you never know what you are getting when buying something.

Oh, and I blacked out the decimal point.   Works like a charm and is within 1% or 1 volt of the reading on my Fluke.     .... Phil

For $15 lowest model, I don't think I'll go wrong. Be waiting for shipment.   Greg

Some cheap designs require it to have voltage sitting there for proper inrush sequencing to take place for the feed back to get started.   Some of these cheap supplies will actually hold the switching mosfet in a DC state and over head the inductor, power tranny or both.   Most variacs have only a little more than input side, I don't think that little over percentage caused the problem.   Jamie

There are some dodgy looking 'tropical fish' caps that showed clear signs of cracking apart even before this incident!
