If you examine the hardware-specs, you can see this is really more like a 2nd generation set ... only now available in 2016 for this price. Click any link in this post for full specs on the sales page (they are currently taking pre-orders).
I will know more after I get mine delivered, but here are my initial impressions about it's features. I suppose these are also the reasons why I decided to buy them :)
- The 480p (DVD quality) resolution screen should be fine for a good picture from the common CCD 600TVL-700TVL cameras that are usually used now-days on FPV aircraft and racers. The screen is also spec-ed at 600cd/m2 brightness, which should work nicely outside with sun.
- The included and built-in 5.8ghz video receiver includes all the common frequency bands, for a full 40 channels of available individual frequencies (including RaceBand). There should be no problem finding a matching empty/clear one for use with your model aircraft. There is also plenty to share at flying field, and it will even auto-select one for you if you want.
- Looks like the front "goggles part" comes-off and you can easily mount the main screen unit on a common tripod. This is good for FPV newbies like myself. We can fly normally line-of-sight (LoS) or look into nearby screen to fly FPV. You can also just use it to "line-up" aerial video and photography shots (which is really handy ... you see what multi-rotor sees). You can transition between either mode as you see fit.
- It says the battery is also included, so this set of FPV goggles is ready to go ... just connect wirelessly to your aircraft.
Oh ... when I ordered them, I paid the extra $2 for Priority Direct Mail and Shipping Insurance. Then, I simply paid with PayPal. Actually, this is what I always do when ordering items from them. I'm in USA (Texas) but In-Stock items ship fast and show-up on my door-step in a couple of weeks (even all the way from China).
The EV800 FPV Goggles work pretty good and picture is clear. Not going to do full review because others have. About 90% of the reviews are favorable and they seem to be working good in the field for most pilots. Latest shipping units should include nice black face pad and external video-in capability.
The main fresnel lens in NOT adjustable, so pilots who wear glasses or who are slightly near-sighted will likely find that the fixed distance between the lens and screen just barely allows a clear focus.
My main use for now will be as FPV goggles on my head. However, the EV800's LCD screen does well in sunlight, so I wanted to try them on my tripod and/or attached to my transmitter. The core display-unit is pretty compact and I like the its "sun-shield" body-case.
For most pilots, the new Eachine VR-D2 FPV Goggles 40ch-DVR will be the better choice because it has a built-in DVR, better antenna system, and the main lens is adjustable. It simply has more desired features for just a bit more money. I have a pair on order.
