I have one
I bought a 16 function 10 QT on HSN after Christmas. Does a great job, does take up a lot of room on the counter.
You have to play with it a bit to get proper results, as the pre-programming is not for all situations. I think the roast beef setting must be for medium, whereas I like my roast that I cook in the PC fall apart done. this takes about 90 minutes instead of the 45 the program sets.
Being only 110V it does take it some time to build up pressure. But I enjoy the automatic part of the cooking where I can push a button and not worry about pressure getting too high. Once the cooking cycle is finished it will begin to naturally drop the pressure which give a little more cooking time, and then it goes to a keep warm function.
One complaint. I have only used it about six times, where it always worked perfectly, but the last time I went to use it the lights would come on but would not heat.
I have to call and get a R/A (Return Authorization) Last time I tried, though the manual said they were in CA, I would suspect it was Taiwan or Beijing. Very, very difficult to understand person on the phone. I decided I would try to get the R/A online.
