While you can't run an electric cooker under cold water to quickly bring down the pressure after cooking, the models we tested come with quick-release pressure valves. Easy as they are to operate — flipping the knob to open — the short handle on many of the models makes it almost impossible to keep your fingers clear of the hot steam as it escapes. This is easily remedied by using a pot-holder or a long-handled utensil, but it can be a little alarming — and extremely hot — if you're not ready for it. The Fagor, Nesco and All-Clad test models had slightly longer handles, which was immediately appreciated.
So what about some of those other functions? Can they cook rice? The Fagor includes a specific rice setting in the display, and all the models except the All-Clad give some sort of instruction on cooking rice in their manuals (the Fagor and Cuisinart are very specific; the Nesco and Deni are much more vague). The results were hit or miss. The Fagor and Cuisinart made great rice the first time out; coaxing better results out of the others might just depend on getting more of a feel for the cooker.
