Hi Guys, we really pride ourselves in the Envy Needles in the cart system which does make a difference compared to others. Our retail cost is higher due to the QC and materials work we put into our needles to ensure safety and consistency. For those that are on this forum and wish to test them out, I'd be more than happy to provide some samples free of charge. Just email me directly at [email protected] and I'll work on getting some over to you guys. We stand by our products and will continue to add more types as we slow roll these out in bugpins, supermag configs, etc. Thanks!
