Keep in mind that we're talking about mass-produced units here, not hand-built scanners. I'm sure Uniden is very much aware of the tarnished image this issue is giving them, and that more than a few Uniden folks are highly embarrassed that the issue wasn't identified during earlier testing.
But that doesn't mean that they can snap their fingers and magically get the problem fixed. It wouldn't help anyone if they replaced the first batch of scanners with ones that had the same problem.
They need time to understand how common/severe the problem is, what was wrong with the original design and/or manufacturing process, redesign the parts, get some built, test them to make sure the new batch is better than the old, make sure that any 'bad' parts are purged from the manufacturing lines, develop plans for what, if anything, to do to repair/replace the initial units, whether to put production holds on the product, whether to recall unsold units from distributors, etc. While I don't know about their internal processes, it seems likely to me that this 'simple' issue involves multiple subcontractors around the world, to say nothing of accountants, lawyers, support people, marketing and public relations people, engineering teams, quality teams, and more than a few managers. All that's not going to happen in just a few days.
Sure, it's annoying to have visible defects in an expensive product, but I have to give Uniden a lot of credit for admitting the issue and actively soliciting the input of its early customers to figure out how serious it really is. Give them a chance to do a responsible job of investigating and fixing the problem before assuming they don't care. Paul seems like a pretty straight shooter who cares about producing high quality products. I'm confident that we'll hear more from him as soon as there is information that he's allowed to share.
