I have owned a vortech and a jeabo. In my mind i do have a hard time with wether or not they copied the tunze. I dont know what the patent violation would be? Yeah its round and has a propeller, but what other shape are you going to make it? I cant see the controller being a rip off either, its just pre set programs, you can do the same with an apex. My opinion is they are very good quality, not great like the vortech. But its hard to justify the high price when i can by 2 or 3 for the same $. Some day i will have money buring a hole in my pocket and i will buy another vortech. For now the jaebos are working good.
Every business has competition, its just hard when it comes from over seas where they can cut costs so dramatically. I think vortech or tunze should fight back with a price drop, or perhaps send in your jeabo and get $10 off, lol. Something to rally customers.
