These are awesome!!!

I purchased this product to drive video projectors in a theatrical setting. Unfortunately outputting from a Mac Pro, through an active mini display port to hdmi to the BenQ projector didn't work. I then put a Blackbird 4K 1x2 HDMI® Splitter
Product 13705 at the end of the 330' run to recompile the signal- and that worked! Definitely test with your own equipment, not all hdmi displays will be able to recompile the signal on their own.

PROS: light weight, tested with 1280x800 px

CONS: need an extra powered device to recompile the hdmi signal

Monoprice sent me a review sample in exchange for an honest review.

Packaging:
Comes in a thing cardboard box. The cable is coiled inside with no padding between it and the sides of the box. Being an expensive cable id like to see some form of protection from shipping mishaps.

Cable:
The cable is a single direction cable, as in it only sends signals one way. The cable is labeled so you know which end is which (Source, Display). The cable is also made up of a black rubber-ish material while the connectors are black plastic and your standard HDMI connectors, however they seem to fit loosely into ports so they could potentially fall out with little force. Now the cable is a slim run so that being said, its pretty tiny and sort of flat.

Tests:
1280x800 Dell Smart projector - Projector picked up the signal right away and displayed an image. Video playback had 0 or ill-noticeable delay.
1080p LG TV with CEC - CEC works as described. The cable was able to send a power on signal from my Tivo box to the TV.
EMI interference - Cable was wrapped around five 110v lines and ran parallel to a breaker box. No interference was discovered while cable was in use.

PROS: - Slim
- Fiber-Optic cable type hybrid, so no real EMI interference
- 330ft of working HDMI cable

CONS: - Single directional
- Does not support Ethernet over HDMI
- Cable heads feel like cheap plastic and can easily be smashed on accident
- Connectors seem to loosely fit inside ports
