"Yes, we're still here" - Jan 27th, >2 months ago. Again. So many people complained about it, and you guys lern NOTHING: it is damn impolite, arrogant, ignorant to take money from people and then let them hang on a thread for months and years.
I accepted that your competence doesn't match the needs of a professional business (it's different from running up some mountains and dreaming of Android apps, of course), that's water under the bridge. Not every climber, hiker, dog owner is an engineer or an entrepreneur. But the ongoing flow of (communication) promises and their also ongoing breaks is, well, nothing but a very bad style. There are absolutely NO excuses for that behaviour. My parents taught me so, but that's probably the habit of another generation.
Meanwhile I built several E-ink driven flying devices for myself and half a dozen of friends (I apologized to those whom I suggested to trust you and your ambitions, and I sincerely adviced the others to stay away from Earl). I've got used to check the website on a regular base only to find that nothing substantial changes - only loads of hot vapor and volatile excuses. I think that the device, should it ever be released, will then be years behnd the state of the art. Anyway: it's not the first money I've wasted. But it's the first time I got frauded by guys of the "outdoor sports community" - sad to realize that common cheating also has reached this biotope.
