I had a fold 3, now I use a fold 5 as my daily driver. No issues with either except I used the 3 without a case for a while and now the hinge is slightly damaged, everything works tho. Love them.
I just love having a tablephone. I play Sky Children of Light on it nightly with my kids. I also use it to remote into anything I need at work and its easy to work off of it. I'll be getting the fold 6 through my company when it is released and still have my fold 3 in storage just in case something happens to my employment.
