Have been waiting to buy the Essential Fire suppressors/extinguishers. Bought 3 units: home kitchen, Airstream galley, tow vehicle-Silverado 2500 HD Diesel. Of course, and thankfully, none of them has been used. Like the small space required, the wide types of fires they can be used upon, the lack of expiration date, the relatively long application duration, the ease of use. Can't think of any negatives.
