Wow, your knowledge of safety, efficacy, claims, the FDA, 510k or PMA submissions is staggering. What you write is a nice thought, but with device design, you need to prove it, otherwise you can’t mention it or you will get a warning letter to cease and desist. Look and feel is a part of the design, but it can’t be used to sell the device.
Ironic getting career advice from someone not in the industry. BTW, where exactly did I write “It doesn’t need to look better… Lets just leave it ugly” ?
