I may be one of the few people here who has actually put out a car fire. I would not recommend this product for the following reasons.
1. Water-based means it'll freeze. North of Washington DC, that means it's useless 3-6 months a year, unless you keep it in a heated garage.
2. The amount of chemical is only sufficient for putting out a pan fire, as in the videos. (If I had a grease fire like that in a kitchen, I'd put the lid on the pan.) It's far more likely that by the time you notice and start responding to a fire, it would be at least 10-20X as large. Seconds count, and I would hate to have to hunt for a second little aerosol can because one wasn't enough.
3. You get a feeling of false security by having something like this.
The fire I put out was in a fellow customer's car at the service area of a dealership, and I don't know if it started from careless smoking or an electrical problem. All I saw was flames behind the dashboard, and I was nearest to an extinguisher by a good half minute. By the time I got to the car the flaming area was the driver's seat and underneath. I emptied a full (large) can, then stepped back while employees took shots with their own cans. The fire department was there in 5 minutes.
A small can like this product would have been a waste of time, and I might have prevented better equipment being used (by blocking the way).
At home: I have a Kidde dry chemical extinguisher in the kitchen 10' from the stove. Another, fresh-charged general purpose Kidde is 10' away in the opposite direction (stairway to basement). Yet another is by the master bedroom. Older, "expired" extinguishers are kept in less risky places, like the attic and basement by the furnace. These still have a charge on the meters, but I don't rely on them for primary safety. (This Woot model doesn't have a gauge.)
As far as computer fires... smoldering wires and power supplies ... the smartest thing is to yank the plug and get the PC out of the house immediately. Make sure you vacuum the inside dust regularly. Custom case wiring only fries if it has too big an amp load, so make sure you upgrade by a gauge or 2. A separate fan controller will usually have an audible heat alarm, so tape your sensors where you expect the most case heat.
PCs properly built are reliable: I run all of mine 24/7 including while I'm on trips. But I'm in and out of the cases on a regular basis, so a lot of maintenance is the norm.
Today's Woot product might be OK for a studio apartment kitchen, but readers should study available products which cost $20-100. to get a sense of the trade-offs. Amazon (Woot's parent) has competitive prices on these other products.
