My impression of Jetboil is that it's grossly oversold, given its severely limited and highly specialized application. Apparently, the MSR version, recently available, is a somewhat better product, but almost equally limited it its actual application.

Wasn't the MSR recalled for safety reasons?

No, the Reactor was never recalled. It got delayed during production for quite a bit though. Originally it was scheduled to be out in spring 2007. Then that date got pushed back because "a minority fell short of a particular worst-case combustion condition test, and produced higher than desired levels of Carbon Monoxide (CO)" during MSR's testing.

You can read the MSR release on that here:

The Reactor finally shipped to stores at the end of August and is now (after months of hoopla and awards and talk) available.
