Of all the things you can build on this site, this is the absolute easiest thing. If you've ever built something else from on this site, you should be able to put this test cable together before lunch. UNLESS your name is Tony. If your name is Tony, I'd implore you to ask "What is DIYRE an acronym for?" Why does this item say "kit" in the title? Under "features", why does it say "Only three parts to solder"? Is there an "Assembly Guide" listed clearly as a resource on this same, clear and easy-to-read page? Without any sensitive parts, resistors to sort, or capacitors to handle with care, I'm shocked to see that there are any reviews for less than 5 stars. I never review anything, but I'm choosing just this once, out of spite for the stupidity of these lesser reviews, to say "For the love of all things electronic, what did you expect"? If you have a problem with this kit, you need to stop trying to build things for yourself. Actually, you need to consider whether you should be driving, cooking or using a remote, because if you have issues building this kit after building a preamp, you are a danger to yourself. Also, your preamp is, I PROMISE, not assembled correctly. Like your mother said, "If you can't find something nice to say, don't say nothin' at all."
