I origionally bought a Runbo X3 with the qwerty keyboard, it worked well, for almost up to a year, but then there was a problem with the charging system inside the phone itself, the battery would take and hold a charge, if charged outside the phone, so it was not a battery issue, and it was not the charger, it had to do with the micro-circuits inside the phone base itself. I took it to a repair shop, and they said that they could not fix it, micro-welding, and they would need the new part. I did right RUNBO in China, but they basically told me, "we are very sorry, but tuff luck for you."
I then bought a CAT C-15, but that died on me (I'll discuss that in their review.
I just bought a RUNBO X5, I do like the Runbo concept and their phones, after three months, I'm getting glitches in the re-booting process, it will attempt to boot multiple times, after up to a half an hour, it will finally boot up, sometimes. Needless to say, I'm not going to ever bother to right the Chinese company RUNBO, and get another "tuff luck, no service for you...." This phone is like a bic lighter, use it till it breaks and throw it away (or sell it for parts on Ebay).
