We pride ourselves on the quality of our wire and our spooling process. If you encounter issues with any of our wire products, please utilize the Support box on the bottom left of the page to contact our support team.

Just a note: The world seems pretty evenly divided between folks who love Kanthal A-1 and folks who love Nichrome (60 and 80). A small number of people claim to be able to taste the high iron content in Kanthal A-1.  Personally, I can't, but... you might. If you are new to RBA's, I recommend getting some of each. (We will have a multi pack of the different types but in the same gauge up soon).

    I ordered the 29 awg kanthal and for the price it is excellent as well as the coil holding up very good. It did not have an oily residue on it eit her but I always like to hit it with a torch anyways. Great product will buy more.

    the best ever.

    Posted by Andrew Harris. on 27th Oct 2015

    The kindney puncher .22 gauge is the best I have ever used. Others I have used have just not heated up like the kindney punchers do. It's strong, durable, long lasting and they are a lot easier to build with. The packaging for the wire is finominal. Other wires u have used were packaged like crap one you get the length you want it just goes everywhere. And it's a pain to to just put it like it was. It just makes a mess but the kindney punchers just are packaged right durbale and last a long time. I would recommend this product to anyone.

    Works great for .5ohm coils

    Posted by John on 29th Sep 2015

    I love that they offer wire in small packs, just to test out a resistance before buying a whole spool of it. This wire is working great for me. Using it in .5 sub ohm builds. Couldn't be happier.

    Good Stuff, Maynard!

    I bought mine here because Kidney Puncher is one of the few sources for small amounts of odd gauges of Kanthal. Their larger spools are reasonably priced as well.

    almost perfect

    Posted by ashlyn on 6th Aug 2015

    Great wire but packaging is severly flawrd, wrapping it aroind a peice if flat cardboard causes a large and difficult to remove bump every so often. The problem it probably lessened the higher guage you go. But even with a drill the 24 guage was impossible to straighten

    Wrapped 4 strands and made a .8 ohm coil rips like a charm

    Good wire

    Posted by Jo Harris on 13th Apr 2015

    I'm new to building and this wire worked well for me. Shipping was super fast and I got everything I needed for my second build in one place. Will definitely buy again.
