Well here is my opinion on these new notes I find them a pain to use. One they stick together far to easy and who wants to give away an extra 100 because they are stuck together. Two they do not work at the casinos, yet they still pay you with them when you win a jackpot. The marking of these bills is in vain as they are not yet into the system so cannot be entered or tracked. I have not yet tried to tear one in half as doing that to a hundred dollar bill hurts just at the thought. Nor have I tried the heat test or the freeze test yet and the washing machine and dryer tests have yet to be done. Now these test will overtime be done as we are curious and long for information I am sure someone in the test labs have been paid a good sum of money to do these types of tests and report on them but of course that information will not be made public. So to sum it up one more time in my opinion these new bills are crap. I have gone in the other direction as most non trackers do and ordered my plastic cards to charge my purchases and then will pay those bills on line and my payroll is now becomeing direct deposit so I will seldom touch real money anymore except when I visit the casino (or ya I plan to quit my gambling ) so I guess I am joining the cashless world. Someting I thought would never happen.
