"If you want a bare bones i4, …..I have many many many and would send one for the cost of shipping. ... It won’t have removable bits, but you just take off your i4 and re use. ... The error 9 Dance is an easy fix. Not fun but easy. ... I have boxes and boxes and will never sell them all."

"I have to babysit the damn thing every time it runs. ... It’ll catch a cable or suck up a cat toy so it’ll stop and I’ll have to fix it. ... Kinda makes the whole cleaning when your gone thing pointless you know? ... I don’t want to make sure the floors are clear of toys and cables first. ... I want it to maneuver around that stuff. ... I think the connivence of a robot vacuum is it can detect this stuff, especially while you’re away and act accordingly."
