Sometimes a temp setting is a mental thing and not a comfort thing.I still have a lockbox and it is never failed, batteries never need replacing and not one complaint.My favorite is my Digital Watchdog camera system.

A simple search around any base will show service members convicted of sexual assault, battery, ect. so are still on active duty.

What does everybody like for battery powered tools?

We change the 9v battery once a year. 

A live stream is available and a motion detector is setup to send 8 sec segments to the cloud which can then be viewed.The battery life is not bad but it depends on the usage.

Other than that just tires, battery and a few recalls.

On your first try spend 600 bucks on a Graco battery powered sprayer with the disposable cup.

I have installed a few and played around with their features and so far MilesIQ seems to be the easiest to use out of the handful i have been testing out, Triplog works fine when i have it setup on fully automatic, but boy does it drain the battery and when i tried to set it up to use a OBD2 dongle i purchased to save power it has not been able to reliably log miles, it seems to miss any trips i sit to long in the car before taking off after it initially detects the obd2 device.. hurdlr seems to be just as accurate as MilesIQ in the fact of logging miles driven and its completely free to use, but the whole selecting which is business and which is personal feature of the app is a bit odd and slow, when you mistakenly swipe one as a business trip and it was suppose to be personal, for the life of me i have not figured out how to correct this in the app and there is no login website to try and correct it either, i am waiting for reply from help request on that step... 

Then, it still always involves 2-3 trips to the plumbing supply store or Lowes.Table saw, chop saw, jig saw, roto-zip, rotary saw, 3 sizes of hack saw, sawzall, router, under door saw, bow saw, chain saw.....Battery drill, battery skill saw, battery flashlight.Many sets of drill bits and screwdriver bits, flat, phillips, star, hex, several pry bars, pliers, pipe wrenches, screwdrivers, wood chisels.......Tape, carpenter's pencils, utility knives, several sizes of tape measure, T-squares, and levels.....Buckets of plumbing tools, spare lengths of PEX, PEX fittings, PEX tool, PEX cutter, teflon tape, plumbers dope, under sink wrench......Electric plugs, GFI plugs, wall switches, wire nuts, wire strippers, and a new light bulb for every fixture in the house ebcause every one will be burned out......Compressor, brad gun, nail gun, finish nailer, roofing nailer, hardwood flooring nailer, assortment of nails, brads, screws, staples and the power stapler to go with them (both electric and pnuematic).Drop lights, halogen work lights, salamander heater, furnature dolly, saw horses, portable propane tourchSanders, 3 sizes, sand paper, power planer.....And there's more.

However, despite having two batteries (I suppose one for the engine and one that runs all of the ridiculous gadgets) it was as dead as my probates.Lucky perhaps because as we were leaving the conference my buddy, the big foreclosure trustee, rear ended my Cayenne Turbo just enough to require body and paint work.
