Query: Lead causes cancer!

These memorex keyboards are okay. The hot keys won't work unless you install the software on to your computer, but the software is memory resident. So it becomes just another program that eats up your system resources. Also for some reason, memorex decided to put lead as a conductor in the keyboards cord, so you run the risk of getting lead poisoning each and every time you touch the cord. You will see a warning to this effect on the cord itself.That alone is enough of a reason to stay away from Memorex keyboards! Even though Memorex does make cordless keyboards, they lost me as a customer due to their reckless use of lead in their products.Not worth the money, not even if it was free. Buy another brand of keyboard. Lead can cause cancer, so enough said.
