Sub $100 kick mic (backup to main kick)

[nuemes]

I've got an ATM25 and would like to add a second kick that has an extended high freq response to pick up more beater. There are a lot of low cost kick mics (sub $100) that claim do this well. Have you had direct experience with any of them?

Never heard or seen that brand before, but the shape looks familiar. Let us know what you think of it if you buy one. The price is very attractive!
