We are a kickstarter project, we cooperation with them is a very good choice. Their bom team are professional and responsible.

They told me they need two days to costdown my BOM list, but they only in 24 hours. We found only 4 part numbers expensive than we thought, last they find some suppliers help me more 3 parts cost down and only 1 expensive then we expect.

Very very good service. I will introduce to other project friends.
