I ordered of NATS last week just to see what the cartridges would be like over the ttec, The next day I had a private message on my facebook which I did not put on my order that they had done all the checks and all was good proceed with my order to send out that was the last thing I was expecting was to be vetted but sounds good to me our supply company over hear wouldn't even bother vetting before taking money so lets hope the carts are good as ill be making a bigger order next time all going good.
