Johnny Rekall "TnX"
All i can say for now since i have yet to use them is, they showed up on time very fast, as well each came wrapped in a small paper packet that is small enough to fit in your pocket. Secondly If these are the right ones i believe they will be excellent since based on the info and exp. i know from other ones i have used. I got them as gifts for other people so i have not had a chance to notice much. Hope this helped.
