Cheap ShotGun Microphone 320E Review ($15.00-$18.00)

Cheap Chinese Shot Gun Microphone 320E OR Professional Shotgun Interview Microphone Uni-Directional System condenser Mic.
I've been needing to get a new microphone.
A shotgun microphone to be used for my Canon Vixia cameras.
I have the Canon Vixia HFR-10, HFM-301 and the HFM-40.
The camera's onboard microphones aren't the best.
So an external microphone that doesn't completely suck and cost too much was
what I was looking for.
The "Cheap Chinese shotgun microphone" is one I've seen on YouTube
for a while now and the results have been mixed, but leaning towards the positive.
So, I thought I'd spend the $18.00 and find out if it can be used.
The price varies on these things and I've seen them so far at $15.00 -link below-
For what I do, this microphone will work just fine.
It's by means an excellent microphone. It's just barely Alright.
It's also $15.00 with FREE shipping from China.
Take that into consideration and overall, it's completely worth it!
I don't know how long it will last, but it seems to be decently constructed.
I plan to buy 3 or 4 more of these. Just in case the life expectancy is low.
The shipping time on these microphones from China is around 1-3 weeks.
3-4 weeks is more likely.
I like it so far.
I translated the Specifications:
