Not this particular model, but I've had a few other models over the years. Such as these below:
Aroma Food Steamer
Richard Simmons Food Steamer
I loved both of them, but the Richard Simmons one unfortunately had BPA in it, and it was way too large for everyday use. However I really loved the digital controls on the Richard Simmons model, vs. the manual dial on the Aroma model. That said, the Aroma model was otherwise perfect - nice build quality, something I would gladly leave on my counter, and it was just the right size for everyday use.
The real big advantage of using one of these, vs. steaming stuff over your stove top, is that these literally start steaming the food within like 15 *seconds*, whereas you may have to wait 10-15 minutes for a stovetop steamer to start steaming food. Plus they cook super consistently. If something cooks perfectly at exactly 7 minutes for example , you can get the same results each and every time - whereas a stovestop steamer might fluctuate if there is a draft in the kitchen blowing the flame or you have it slightly higher or lower than previous times.
These make rice perfectly, and they are also fantastic for hard boiling (or soft boiling!) eggs, and gently steaming delicate pieces of fish. One thing I would caution though is to use stain resistant bowls inside the devices, particularly if you are cooking items with turmeric, curry powders, fresh carrots, beets, etc... as these will permantently stain the main unit's plastic parts rather easily.
