The 3M is produced by #M as it is a big company by itself. SolarGard is owned by Saint Gobain performance plastic company https://www.plastics.saint-gobain.com/. Sun-Gard is just another brand name for Madico, which is a big company that produce tint film mainly.

The name you said copy is actually original. Ecotint (M) Sdn. Bhd is the distributor for Madico film.

Now there are many brands in the market. Many want to established own name by buying China products.    They maybe good and may not be as good. Just stick to known brand. If they have warranty, why not. The problem with unknown name is that we don't know if the brand will still exist within warranty period. 

it's ok. few hundred bucks damage for a lifetime's lesson. next time, go straight to the ori stuff better
SA get comm paid by shop. this one is outside from their car sales commission. SA dont spend a thing. all they need to do is bring the customer to the shop saying he/she recommend this shop and just by quoting his/her name, can get "special" price. that's how they identify who to give comm to.

That one you need to ask cococonutseller
