my favorite was in the Alaska Air board room in PDX one EARLY morning.. the sign in for the room is a finger print then your name pops up on a I pad like device. lady behind me says are you the Jay from BP..

Left to her own devices, knocking on a tenants door who is late on rent by one day, would involve a ball bat or a golf club beat down as a warning that things would be rough if it ever happened again.

This device does a lot and if any of you would like more information about how to get one, please PM me. 

I have the municipality unlock the meter valve but I turn it on myself so I can check things out and make sure all the water devices are working properly.

Quote from @Jacques Villars: The 1% rule is a filtering device, not a method of calculating return.

Power plants have many scrubbers and devices to recapture both the energy and the pollution to clean it further before emitting it.

Turn you idea into a real system or device or whatever it is and get it patented. 

To quote the great @Andrew Fidler “43607 is 75% war zone and the majority of the area qualifies for me checking for spare magazines for my personal protection device before exiting my vehicle.”Read more herehttps://www.biggerpockets.com/...That being said I have a hand full of properties by the university in 43607 it’s a great rental area to the east of UT and west of Calvary Cemetery.

My number one piece of device is to not fall in love with the property but fall in love with the deal.  

Countless companies making various face shields, masks, reinventing new kinds of devices to evolve these, bed sheets, tubing, on and on and on and on.
