installing them is more expensive compared to horizontal systems. i used a pressure cooker for years in my “early married” life, but it was the kind of scary kind. it’s cold and grey, an amazing change in just a few minutes. apparently you can take lessons and get rentals in boston for a few hundred dollars. i knew pretty quickly why they did not smell like smoke. our faith is never static, but living, breathing and growing. but it's really hard to get past the device's $800 price tag ($600 with a two-year contract—which actually puts you on the hook for much more cash).
