Thank you very much for your advice supported. For this case I have to present to them again maybe on next week.
Because this week way to their factory have deposed government rally.
As last time I talked with them, They told me about budget will going to next year. They have to prepare about specification of the machine
for "control spec." This is good chance for us to make a lock spec.
If I have any update, I will let you know.
Best regards
Perawit S.
