Rasberry Ultra drops supports SPAM Scams. They break into your e-mail then SPAM everybody you know with their adverts. I have no idea how good a product this might be, and I never will. Anybody who uses this kind of sales tackic is to creooked for me to ever trust. Neither should you.
Consider; they break into your e-mail account by hacking your password, then shoot their bullshit to all of your friends. Now you have to change your password, inform your friends that they may have been hacked as well and report them to your IP.
Do not support these ass-holes by buying their questionable product.
