Hi, I am seriously thinking about getting Fastbraces. I have been doing some research but there is not really much to find. I feel like mostly ads.

Do you guys have any opinion of Fastbraces? Do you think it really works well without any side effects?

Or Anyone done the Fastbraces?

FYI, I am 28 now and wants to spend less time on braces if possible! I do not have overbite or underbite. Just crowed teeths mostly upper front part 

Any help or answer will be appreciated!

Thanks
