Until when is the oxygen trial license v12 available?

Dear Techyv members, I hope everything is fine. I'm interested to know when is the oxygen trial license v12 available? How long is the grace period for this trial version? Is it any good? In terms of customer support, is it reliable? I'm curious to know about its performance. If you have tried this, please kindly share your experience about it. What are the issues the you encountered?
