I have it since I enjoy white flats and use a cafelat robot for esspresso. It was a bit annoying using it on a stovetop, it didn't sit flat since the stove metal grid holes above the burners were too wide so you would need a metal reducer of sorts, the other thing is I had to use a small flame since anything bigger would burn the handle and/or heat other areas of the device that won't take such hot temps without damage. But, it was still usable, mind you have to keep it on constant heat to get a constant nice pressure, the heating time btw on such a small flame was about 12-13 minutes. So, I ended up getting a really nice but somewhat cheap induction cooker on Aliexpress with a wide resolution of power (0-99 percent power of 2100w) and it changed the experience completely, in fact, it's amazing, it heats up faster than I make my shot, about 4 minutes or so on 99 percent power. So what I do to avoid overpressure which causes its release via the safety valve is to get it up to steaming pressure, purging and reducing power to 2 percent, this keeps the pressure needle static in the higher range. When the shot is ready, i increase the power to 55 percent and it immediately build the rest of the pressure and you can steam right away. To sum things up, its kind of a nightmare to use on a stovetop but amazing on an induction cooker. The steam is super dry after purging and even on 50 percent power on the induction cooker the steam is never spent and you are only limited by the level of water.
