A big thank you from us. The commercial feet look AWESOME and the stainless-steel parts look AWESOME as well.We are so pleased with everything. To focus on the stainless, again -we are so happy with the samples. All the cuts and edging Al dging and edging are great and we like the material a lot. We think there may not be much of any changes from what you sent. In the next few weeks, we will complete these items on our end(we want to add scales to the handles using our material).Oncewe test out how we want the final product to look, I will come back to you with an update and a PO.

I'm a mechanical engineer and inventor of the CB company.My experience with Eppo has been fantastic.I communicate mostly with the fellow that goes by Sam and right from beginning I told him that I was coming into it with limited experience in marhufacturing at scale. They helped fill in the blanks,providing options ang giving recommendations.I and a few thousand customers have been satisfied with their work and I'm actually still manufacturing with them so certainly not complaining about quality. They have met every single timelire they gave with extensions only being a result of change orders in design. They were flexible with payrnent terms as well which was awesome on my part to get things going before I had raised all the capital.

We have been working Eppo for the past 6-8 months.I would agree, they are very transpareent with pricing. We have two injection molds,one that was made from another company in China and one from Eppo. Both molds are now with Epposun because we had a bad experience vvith another company. In my opinion, they are highly skilled in injection molding. They also have skilled engineers. So far they have made us around 10,000 units and are helping us design three other products. However, they have the capability of manufacturing larger orders. From whatI can tell they keep your information confidential and are very responsive. What has impressedme the most is their client service.I personally feel they make an extra effort to work with their customers.My project has over 18 components need to combine togther by ultrasonic welding,soldering, laser engraving and packing, atter get the products we believe they have done a good job on quality control.
