// Satisfied Clients

Hear from our Satisfied Customers

That’s amazing! After changing the original design from stainless steel to injection molding, the product cost dropped by 75%. Ideal gave us a lot of great suggestions for our previous design, and tested both the prototype and the first batch of samples. Everything was perfect, and our new product went online a week ago. I’m confident that the lower price will make our product sell like hotcakes in the coming time!

John Thompson

John Thompson Product Developer

At first, I was really taken aback. I thought I was in big trouble, as the finished product was completely different from what I had envisioned! The surface treatment was completely off. Well, maybe there was a misunderstanding during communication, and we had a different understanding of electroplating. But thankfully, Jancy helped me resolve the issue thoroughly. They managed to remake a batch of goods within a week, solving my major problem. Although the process was a bit rocky, the result turned out well! Good job, Jancy!

Julia Western

Senior Designer

Ideal’s professionalism and efficiency have left a deep impression on me! I received quotes from nearly 20 suppliers, but most of them provided very general prices. Only Ideal provided me with detailed quotations and modification suggestions. They mentioned having over 30 years of experience in the injection molding industry, which is very convincing! We’ve had a good start, and we’ll choose to further collaborate with them!

David

CEO

Delivery： Fast inland delivery from their warehouse to my motor factory. Quality： Extremely good quality at a reasonable price point and bulk price quote. Design： Great sheet metal design flexibility. The bracket was designed in-house, and the design was finalised by their engineer shortly. Service： Great customer service. Thanks to both Fred and Crystal, I was able to put in an urgent order and send the parts to my motor factory.
