After reading countless posts and opinions on FPV google options, I decided upon the HeadPlay HD goggles. I purchased the HDMI add on board from DJI and installed it on my remote. Fairly simple, but required a specialty small screw driver set, which I had. The HP come with no wires to connect, so I had to purchase a mini HDMI to miniHDMI patch cable. Once I charged the battery, I connected it to the HP's and they powered up (there is no on/off button). The first thing I notices was that the menu is in Chinese. With no directions on how to change the menu to English, I fumbled around for 15 minutes using trial and error. Here is how to get to the English menu: Press menu button. Press Volume button to select the "paint palate" icon. Select the first line with the up/down button, then press volume button. I changed a few of the settings to get a better image, then selected HDMI as my source and plugged it in. It lit right up (I have heard of issues with older firmware, but mine worked perfectly). I did change a setting in the DJI GO app to allow HDMI simultaneous out, which appears once you have the HDMI board installed on the remote. The next thing I noticed is that everything was blurry, but that was a function of my eyes, not the HeadPlay (I'm 47). A focus adjustment would be a nice improvement. I jammed in a pair of reading glasses for the time being (they don't fit well) and wow! The view is incredible. Much richer, clearer and larger than FatSharks. The advantage FatSharks have is the form factor (my wife was making fun of me) and the ability to change diopter settings. A company makes a lens for the HP's, which I ordered and will hopefully eliminate the need for glasses. Flying FPV wasn't really difficult or disorientating, and the OSD on screen was fine for my needs. I could really see well and flew in close to the treetops and through my yard. I was able to be very confident because of the lack of delay on the screen. The bird seemed to immediately respond to my inputs. I ordered an extra battery, as the HP's eat through the battery in about 40 minutes. There is no warning when the battery is reaching the end of its charge; the HP's just turn off, which can be disorienting. There is a small battery buzzer that can be added on to the battery to warn you when you are reaching low voltage, but I haven't ordered it yet. If you are on the fence, I hope this helps. As of now, I rate them as pretty darn good, perhaps the lenses will change that to fantastic. I will update this post after I receive the "Rho" lenses.
