This is my second acoustic pickup, so I haven't much experience in this. But I've noticed it has a very wide frequency range. I play on 2 steps down tuned guitar with 13-56 phosphor bronze strings, and this pickup gives quite rich and clear sound on lower notes that the previous pickup lacked.
Unfortunately, it's picking up noises from radio, cables, wi-fi and other electronics, and i don't think it's possible to shield it on acoustic guitar. But SNR is bearable.
So, if you're searching for a good pickup but have small budget, this is what you need.
