View online video for operations. Different slots available for different sizes but have to be put in proper corresponding slots, Maybe I got a bad one. Get different capacitance readings depending on slots used. Also, all capacitors showed zero ESR. Tried polymer, electrolytic. I also tried using every slot and slot combination on the board just to make sure I wasn’t missing something.Fun little puzzle to put together (no instructions) but questionable accuracy. Not worth the hassle of returning, I’m sure the seller loves that. In the trash.

This was an easy and quick little project. There is absolutely no soldering work to put this kit together. The majority of the work is spent peeling off the protective paper from the case in order to assemble. There are NO instructions included, but it wasn't that hard to figure out. As another reviewer indicated, the battery is loose inside the case after assembly, so I used a bit of foam to keep it from moving around. I tested the operation of the unit prior to assembly and it worked as described. The accuracy of the unit is fairly close, but probably the best use is for general component identification. A resistor tested at 4703 ohms and 4679 on my multimeter, so that was within about 1/2%. Nice and inexpensive little kit.

I really like the Mega328 Component Testers in general.They are reasonably accurate, the display is large, and the green backlight is very bright. Even the graphics displayed are extremely readable, unlike some of the fancier colored-screen testers, which have smaller displays and are harder to read.Oh, and the price is incredible for all it does.I believe this particular kit is better than the others available on Amazon not only because of the lower price, but also because the unassembled pieces come in a separate plastic storage box with a hinged, latchable lid, so once you assemble the tester, the entire assembled tester and its instructions can be stored in the supplied storage box. This is perfect for protecting it from dust, dirt, and chemicals when it is not in use.

This one came with the case that others charge you extra for. Went right together and works well. Identifies components and the readings are close to what's marked on them, and close to a multimeter value, so it is accurate. Identifies transistor type and gain, which is a huge plus. Overall not bad! Works great for what i need it for.
