Pretty standard fare, and exactly what I wanted and expected.. Small, potted, high voltage, step-up transformers. Quality seems fair to good, especially considering the price point. I haven't tested the input current yet, but my tests were done at 6VDC on an HP 6281A, in open air I got about a 15mm spark. The blue tape in the picture is mine. These have no markings whatsoever, and I didn't want to carve on the case. I don't know how thin the case can get before stray voltage becomes a concern. I lack the equipment to test the output voltage and current. While I doubt the 1MV, the spark is thick and healthy with a nice crack. I'll be interested to see what kind of duty cycle I can get out of them if I can keep them cool. A note on any transformer, running a transformer without any load will destroy it. When I got beyond spark distance the transformer hit a high note like a castrato. Keep the leads in spark distance or keep a load on it, although I'm not sure what kind of load could handle this power. Now I'm off to scare the girlfriend.

So I bough this for the little sockets that fit on the wow stick. The whole kit is pretty nice, the spreaders and spatulas are surprisingly heavy and the ESD tweezers seem good quality. The flex shaft works quite well. The pry tool is a bit flimsy though.

Far louder than I thought it would be. Use a magnifying glass, line the part numbers up to the board, and solder. Pay attention to the orientation of the transistors, the grounding pads face the outside, and don't insert them so deeply you can't get the heatsink on. Depending on the style of heatsink you may have to put attach the heatsink before you solder the transistors in place. It's louder if you let coil arc into the air than if you ground it.

I got this with the tiny scope like everyone else. The MCX side seats well, and make good contact. The same can be said for the BNC side. It does exactly what it was sold to do.

I haven't tested the input current yet, but my tests were done at 6VDC on an HP 6281A, in open air I got about a 2cm spark. The red tape in the picture is mine.

One orders from Banggood with certain expectations, this item beat all of them. The bits are high quality, and hard without being brittle. The handle is comfortable, easy to grip, and easy to get leverage with, far easier than most mini-screwdrivers available stateside. This is definitely a bargain, and I highly recommend it.
