This device was poorly designed with tiny conductive dots that touch only the tiny corners of the circuit board contacts. The new ButtonWorx™ membrane has a larger contact pad. ButtonWorx™ will never wear out! IMPORTANT: Letter Mail Shipping Policy **
If you do not select a different shipping option at checkout. Letter mail will be the default.

• Limited Tracking
  Tracking only updates at major sorting machines. 
  The "Delivered" update is an estimate - NOT a fact
  It is VERY common for letter mail to be delivered many days AFTER the delivered update
• Claims must wait ** 15 DAYS **
  Please do not open a claim before 15 days
  eBay forces a wait time of 15 days before a lost or damaged order claim can be opened. 
  If a claim is opened early, I will ask you to wait.
