had issues with putting the DIY kit together every time i’d ask a question regarding the kit and putting everything together i got a reply fast which helped the process customer service at its finest
As the title says, the instructions were very clear and first timer friendly. Emails were responded to amazingly fast (under one hour)
Packaged very well and shipped quickly came unexpected! Watched live on Instagram to build it the same time with all recommened tools. I crimped 3 of he wrong clips and had to stop the proccess, however this was no problem, contacted John, was able to order extra pieces immidiantly to ship on the way! He was completely understanding. Instructions are very easy to fallow regardless. Such a simple great MOD, will be back for more goodies!!
Best MOD ever! If you have any experience doing electrical splicing, I recommend this,easy to do!
