China electronic product has been improving a lot for a decent price. Don't go and buy those super cheap item, definitely sucks. Find those are decent price and many ppl uses it globally.

like the say "Quality item doesn't come cheap"

I am amaze when I bought the china vape back when vape craziness trends around. The built quality is there, fine workmanship, good material. After that tried their phone, and yes the quality is quite good and improving as we speak.

I'm interested to install 70mai 1s at the rear of myvi, is the Ori cable sufficient enough?

Yes
usual line is above the headliner

Did that on my civic and the cable is routed down A pillar, behind glove box

though my 12V is down there in the front of the mid console

where is yours located?
