   Yes, I agree, but as I am an employee of a different part of Ultra, I am not best placed to fix it! It is quite embarassing. However, I am working on fixing some links that have broken due to Ultra having reworked their web site, which I don't think compromises neutrality as it is a simple correction of links. I have not got time to do all the links right now, will be back later. Hopefully someone will be along with the time to re-write the whole thing, as there is interesting technology here, and we really do not want to look like an advert, just present the facts, whatever they may be. I am not an expert in this field.
