I hit a need for numba for the first time the other day. It installed perfectly with pip install, and took about an hour of fiddling to speed up some numpy stuff by a factor of about 30. The numpy stuff was already vectorized but still slow (i think) because it required intermediate allocations. Numba just worked, with a very straightforward implementation of my calculation as well. Really cool piece of kit.
