Yes it is important to get someone who is experience n provide good after sales service. In JB avoid Maxcon, maximum conman.

By the way how u guys prevent break in from the roof? NOwadays with most houses protect by alarm system, burglers are coming in from the roof.

Thanks for the suggestion but I already did that, put 2x nv5 about 7feet above the ceiling. But still feel insecure. Was thinking more of some barrier.
