As usual KB3D knocks it out of the park. This is a great site. They usually always are super fast with shipping and great with communication.

I really like your company i have ordered parts from multiple vendors while making my boron trident, your parts and shipping have been the best!

Amazing company! They noticed I ordered two separate shipments and combined the two and refunded me my second shipping fee. What company has that attention to detail anymore. Fantastic!!
