Couldn't agree more!! I tried the Epson BT-200's a couple of years ago and was impressed then. I think the
BT-300's are AWESOME for drone applications. The picture quality is Amazing IMO when paired with the appropriate shade - I like the one included from Rochester (looks cool too
As for the criticism/concerns - To each his own... Would I love to have these for $600.00? Yes absolutely! Do I think that's realistic given this is a high quality, complete package, and will likely not be sold in huge quantities - NO. Heck, some cell phones cost more than that these days...
Would I like to have the latest and greatest processor, operating system, etc.. Of course! Is it sufficient in its current form for our purposes? IMO - YES.
My experience with the glasses running the latest DJI GO 4 App (4.0.5) has been ALMOST perfect. As previously noted, the map is currently not displaying correctly. I would expect that to be corrected relatively easily and hopefully in the very near future. Honestly, for my purposes, the map is of limited value, I can either see the Mavic's location in flight or I'm looking at an equivalent 82'' inch screen through the glasses of what the drone sees!! I know EXACTLY where it is.... NOTE: I also tested the RTH feature to ensure it was just an issue with map display and not actual drone location. RTH functioned correctly confirming this is just a map display issue.
As far as the touch pad use - Frankly, I find it fine. Is there a trade off - Off course there is. Similar to the difference between using a touch pad vs mouse on a laptop or even more so, a touch pad vs touch screen. I personally do not find a need to go deep into the application once I'm in flight. Most of what I need to do/change can be done on the Mavic controller itself without a need to interface with the application.
Now having said all that - If you're into true cinematography or Litchi missions, a tablet will certainly serve you better. For me however, I don't like having to constantly look down at the controller and then back up at the aircraft. As a retired Army Pilot (Cobra/Fixed-Wing) who just wants to explore and capture some really cool pictures/video and get the aerial perspective I was use to seeing on a daily basis, the
BT-300's can't be beat!! .
Keep in mind these can be used for MANY other things as well! I have DirecTV, Amazon Prime Video, and the UFC App loaded as well. What a cool way to watch TV, Moves, Fights, etc while traveling, on a plane, the hotel, the beech - Anywhere! Too bad I can't where them at work... LOL!!
Also, you don't need to use the included wired earbuds. I use a set of Bluetooth wireless earbuds (Jaybird X2's).
