I'll start:
1- Opting out of ad emails actually stopping the emails...
Bought a screened canopy from QVC last weekend. Been getting 2-3 ad emails every day since.
Yesterday I opted out.
First two emails this morning were ads from QVC...
2- LED light bulbs lasting 5 to 45 years... yeah, right. The words "junk science" come to mind...
After less than 2 years of service many of the LED bulbs in our house are doing the strobe-light thing. Not conducive to the wife's chronic migraines... Also not conducive to the high prices for them... example, I paid like $60 for an LED lit floor-standing magnifier to help with painting small engraved items. It started strobing at about 2 years old, and there's no replacement lighting for it.
I'm getting longer life out of the twisted CFL's...
Both of these get hearty from me.
