Braille displays

Good afternoon. i have an iPhone 4s and am exploring my options for a Braille display. I would like the pros and cons of using the brailleNote Apex, Braille sense OnHand, braille Sense U2, and the new focus 40 blue. Is there a device that works better with an iPhone and other i devices? Thank you.

Hello Sara

Dear Sara.
Good day.
First, are you looking for something affordable, easy to carry and powerful?
Provably the BrailleSense on hand is the best. It's very user friendly and works great with all iOS devices.
If you are looking for a bigger size of a braille display and want to use it for other perpouses such as taking notes, studying and teaching then the BrailleNote Apex is best.
Hope this helps.
Regards.

nothing is "the best"

I don't believe that comments as written above can give any indication, and I would also disprove their factuality. Nothing can be the best braille device in all situations. Now for my advice:
This all depends on what you want your device to do on its own and how big you want it to be. There are basically three classes of braille displays:
1. The simple braille display. These include the focus 40/14 blue, the refreshabraille 18, the displays from handyTech and baum, etc. These don't do anything on their own, but they can serve as displays and keyboards for the phone.
2. Semi-autonomous braille displays. I'm sorry; the only one I know of in this category is the Hims syncBraille. It doesn't do much on its own, but you can edit text documents, at least I think so. I've never used one, but they are pretty popular.
3. Full note takers with a braille display mode. This includes the braille note and braille sense models. They have their own operating system and applications. I don't believe these are great choices as they usually have an even higher price tag, and the phone is already handling the enhanced software system.
