Mini HDSDI to HDMI converter possibility?

I was wondering if anyone has had any experience with these inexpensive Chinese made hdsdi-hdmi converters.

I would like to use my Zacuto EVF with my BMC (when I receive it). I will already have an external 12 volt power source on my cage rig I have built for the camera so powering it will be easy. The price is very attractive ( I have seen them for as little as $131.00, less than half of most of what else is out there. I really don't want to spend a lot of just getting my EVF to interface. If I was sending the signal to an on set monitor I might be concerned but this is only to get my EVF to work.
Here are the specs on it:
This is HD-SDI digital video to HD-MI digital video converter box, this converter is specially designed for HD-SDI high definition camera connecting to large size HDMI plat LCD TV.
Features:
Input: HD-SDI
Video Format: 1080P@25/30/50/60; 1080i@25/30/50/60; 720p@25/30/50/60
HDMI output: HDMI without HDCP
Data Error: Auto detect
Cable Lost: Auto detect
HDMI Port: Auto detect
Power: 12V 300mA
Body construction: Aluminum
Protection: Indoor use
Temperature: -20C~60C
Dimensions: 115mm X 64mm X 27mm
Weight: 120g
Thoughts or previous experience anyone?
