It's decent, but acts up sometimes
I got my optimus one in April 2011 from Koodo. It was working fine but after 2 months, everytime I would charge it, it would freeze up when turning on. The only to fix the freeze wud b take the battery out...which was a pain. Good thing Koodo replaced it with another after constant heckling. everything else on the phone is great.
I'd give it a 7/10.
