Entry-level device, do not expect more.

This is the entry level, very light, very sensitive, quality / price ratio. For the report in perturbed sound environment, use only if the gun-microphones or wire lavalières or other devices are no better. In institutional, gives a small side "pro" who will end unfortunately not on the soundtrack. Saves post-synchronization possible. In light of all these observations, and with the awareness of limits, product to recommend for cheap, delivered on time with good packaging.
