Rockmars company shut down 2 years ago. Yes they had quality but there must have been some reason for them shutting down operation you can guess what that was. I have no idea either but company achi ho tou band nai hoti there must have been problems. Now rockmars ka apko aik do shops pe hi milay ga jo pehlay ka manufactured hai new nai milay ga ab.
Yes Rockmars > Delson only if rockmars was still alive. Out of the current options available
Delson > V7 > unbranded chinese stuff. Unless you get stuff from people like JDM experts. They also sell lcd but they are korean made i think and they have been dealing in the same brand (dont know the name). But its a good brand which is not available anywhere else other than JDM experts. and no one know which brand that is. Lekin JDM experts k paas panel wali (non universal) Swift k liye hai nai so delson best option so far
