Not much to say, they only work as long as you understand the limitations. I'm switching from these adapters to 6" HDMI cables to monitors, I haven't tried longer cables with them. They support up to 1080p, so if you're looking for a higher resolution, you'll need to look elsewhere. I wouldn't recommend these or similar pigtail adapters if you plug and unplug them frequently, for fairly static setups they work fine.
