I just refunded someones order...I could have sent dozens of these things out, and would confidently say they would have been the best mod the recipent owned...if you watched the sucky youtube vid you understand. I found room for improvement and decided that with all the work involved i needed to go ahead and do what i felt was right..and i held off sending out any more devices. I am willing to customize the device to an extent for no extra cost, and this is time consuming...there are three people here who i told to go ahead and make payment on site.. soon after i was able to find a reliable source for tubing. Thank you for your patience, I will create a 60$ discount code for you three tomorrow,(enough for an extra battery tube, or naval brass switch etc) or you can just e-mail me what you would like. if your other tube is to be anodized, i will anodize the extra as well. Ahem..(southern accent) This aint Wal-Mart folks! its a real life greasy loud machine & Fab shop. My intent is not only profit, but to build devices that are the best they can possibly be.It cost me a total of $580 for canceling an order and the extras for a few people. (for doing the right thing) . maybe i should have sent some of these things out anyway, knowing they could have been improved??? Nope, I have a conscience, and am not a crook.....Quality will always come before quantity. That being said, adding the CNC will increase production drastically. I will give the postman some titanium this week.
