Kit works, but be careful.
Kit has 2 circuits, left side is for transmit, right side is receive. Kit requires transmit signal for led to work, up to 5 watts. Both sides work individually, by flipping toggle switch on top. No internal power supply.When mounting variable capacitors, be careful that the holes are not drilled too large, or mounting screws will contact and destroy vanes. Use small washers as spacers if needed. Also, case has general purpose mounting tangs inside that will have to be ground away to mount variable caps. properly.Instructions have pretty good pictures, blow up as large as possible for assembly guide.Watch every YouTube on this kit you can find, there are several.Tuner works ok, but and switch and var. caps are cheap, may not last.Requires PATIENCE!Not to supplier. A Bill Of Materials (BOM) format for instructions would be more helpful.

Good value after findinng instructions
This is another of those kits from China that require a web search for instructions. Once you find the YouTube videos and an instruction pdf, in Chinese, you can get a great buy for the price. It does work.

The instructions suck!!
The instructions suck!!!!! Like many others the Inductor is a tedious job at best. The finished product makes it a good buy.

The capacitors were difficult to install mechanically so I trashed it.

Wow. No instructions included at all. We had to use the instructions mentioned by jwh in another review.http://mrdys.51.net/qrp/AntennaTuner.htm

Antenna Tuner Kit Assembly
I purchased this kit from a different store. The directions are worse than bad. If you have a good back ground working with electronics or ham kit building you can build it. Here are some helpful sites:http://mrdys.51.net/qrp/AntennaTuner.htmhttps://app.box.com/s/so3ov9b0zjsz3dysj1s9https://www.youtube.com/watch?v=jdFTwGv-CZYhttps://www.youtube.com/watch?v=hYeb-XN80FAOne last hint. Mine had a stop on the twelve pole switch. It could only step to four positions. Remove the nut and lock washer from the switch. Remove the next thing. It looks like a washer. It is the stop. It has to be removed (do not reinstall it!) to allow the switch twelve switch positions.Good luck
