Like you many TOP MEMBER OF Digit Technology Discussion Forum advice to buy product from SMC international but they DO NOT give after sales support like RMA/WARRANTY, if required RMA for customer than he/she have go to Manufacture support. But some online store accept faulty product and they process for mnf. RMA.
e.g.
1) SMC not mention warranty in their product details webpage.
2) Nobody can fill-up to end, SMC RMA form in their webpage, Issue *-- its tricky.
RMA/Support
3) After return faulty item to SMC, never send BACK to you, if send it will another problem or same.
4) They stop communicating with customer if problem arise.
5) They do not print Seriel No of product at their invoice to get warranty.
But great advantage with SMC is
1) Product very 1st available in India which is not other online shop
2) Price is lower.
