As a reviewer who knows Kevin personally, my characterization is that he and company are old school on communication tech, but rigorous on wanting to maintain quality in equipment and communication and customer satisfaction when established. Kevin is among the highly trusted members of the industry in his relating to me in reviews over the years.
There have been long gaps in communication with many small manufacturers over the years. Almost universally they have shown integrity ultimately.
I do not know the current operating conditions as it has been several years since the reviews. Even back then I had to sometimes try several times to have a conversation. If you can put up with some dead air space, it'll be ok.
