“IG8 was helpful in taking our concept, improving on it and then producing working units in just two months. This is quite a quick turnaround time. We used other vendors in the past and it took twice as long as was three times more expensive. Keep up the great work IG8!”

Lukas J.Concept to Mass Production in 2 months!

“IG8 has truly performed in the top 3% of the suppliers we’ve worked with. They meet deadlines and deliver excellent work in a cost-effective manner. Their Western project managers are a big asset as they improve communication and eliminate the chances of error when dealing with the Chinese factories.”

Michael M.Performance in the top 3%

“We’ve been using IG8 for several orders now. Production quality is always meets our expectations and there are low defective rates. When a minor issue does arise, IG8 gets on it immediately and makes sure that it doesn’t happen again. We look forward to working with IG8 for many more years to come.”
