I bought an older Casagrande C6 through Sigma and it turned out to be a excellent quality machine. I know these machines and if they are looked after they are excellent machines. This one was exactly as advertised low hours especially for the age. Can tell by how it works that the hours are genuine

I want to express my appreciation to Sigma and commend you for the high level of integrity exhibited during our business. You did not only give me sound professional advice, but you also did not betray the mutual trust we had during the transaction. What you advertised that I paid for, is what was delivered to me in Lagos. The equipment is on site working very well. I therefore make bold to say that dealing with you is as good as going to bed with both eyes closed. Once again, thank you.
