My first Double bass pickup, picked on the strength of the sound sample on here, and the affordable price. Installation is very simple, even on my bridge which has pointy wings and a big gap. The strength of the signal is high enough to be used directly into an amp, but the sound on my bass tends to get a little boomy at higher volumes. Most amps can dial that back, so not much of a problem, especially if you are using a hi-fi or acoustic amp.
