I'm using one on a one-tube board I am making (a bit excessive for one tube, but it is small, 5V and can sink a decent current). At the moment I have one on a breadboard. They work as advertised! I picked up some Adafruit QFN44 adapters from digikey and had a stencil made to do the reflow with: I *have* hand soldered chips this small in the past, but it wasn't pretty and not always successful. A stencil makes it very easy.
I used a reflow griddle, which is fine for small stuff that I can pick up with kitchen implements. I am thinking I will need to upgrade to an oven for the actual board though, which will have a bunch of QFN chips on it. Probably too big to pick up with the kitchen tools I have! That's why I am on this thread, I was looking for some info I saw pass by a while ago.
