I bought the Astroslide and still use it..
I crowdsourced the AStroslide on Indigogo. But never received it from them as the company went tits up. I spotted one on Ebay so got that and have been using as an everyday till now and been very happy with it. A few people are rather jobsmacked when I get the keyboard out.
Luckily I got a refund from Indigogo as there was some cash left over, but others were not so fortunate.
Every morning on turning it on the Planet update app vainly tries connecting but no joy.
Recently i dropped it out of my pocket onto the garage floor and bust the screen!
Now waiting for a fold 7 to replace it.
