I had a OPO & OP2
In fairness the OPO only remained in my hands long enough to list it on eBay as I'd had to replace my phone between ordering and delivery and it took many weeks.
The OP2...it started off as a decent phone. One of the reasons I purchased it was the promised regular security updates but they were few and far between coming roughly every 4 months.
No...my view of OP is that they're a massively successful marketing machine that just happens to produce a few phones.
