I have these on every lamp in the house, only need one remote per room.
Amazon -- Ivation Programmable Wireless Remote Control
Use this every single day for my daily 16oz of coffee.
Amazon -- Zojirushi SM-KHE48BA Stainless Steel Mug
I've purchased 14 of these since my original as gifts for friends/family.
My original is two years old, recently had to replace the lid because the latch broke falling off my desk. They sell all the parts separately.
