I have a Rock xtreme 64 and it has a problem. It was repaired and returned with the same problem. it was sent back and signed off as repaired, then Stone noticed the problem, so they fixed it, signed it off again and sent it back. It still had the same problem so it went back. They said they had no idea what was the cause and would change the base. I asked what that meant and they said all I would have left of my old laptop would be the hard drive and the lid. I asked about the motherbpaord and they said that would be new. It came back, still with the same problem.
However, whilst the jobsheet was signed to say the work had been done, what I got back was like something out of a skip. The keyboard was second-hand, showing wear marks, having cat hairs under the keys and having brown food squeegeed under and in between most of the keys and with paint scraped off the keyboard base leaving bright metal shining through. Around the speakers, paint has been scretched off. As for the new motherboard; it was made in 2005. All the ports are integral to this motherboard and many show signs of considerable wear.
So, Stone do not know how to fix certain faults.
Stone fix warranty claims with second-hand parts.
Stone lie about the work done.
And, guess what, they want me to send the computer back to them! I have asked for a replacement and they have refused.
If anybody is in doubt about Stone, my advice, based on experience, is stay well away. I hope this posting saves somebody else the stuffing I have experienced.
