Just COD with seller, below are my comments:-

1) The product is good, after applied the conditioner, result is obvious!
pickup smooth!! Worth the penny! More than Worth!

2) Seller is very responsible, did offered value added services(100% free) like:-
i)Engine Oil Checking
ii)Car Related Training
iii)Some tuning
iv)Identified car's problems

For the cost I paid, this is considered extremely cheap, therefore, potential customer out there, please consider this product and MUST buy from this seller!!!!!!!!

*I own the worst waja according to seller, but after treatment ----> Upgrade!!! I own a good waja.

Next upgrade is ROM reflash!
