Unfortunately like many great ideas, Sun Lizard didn't survive in the
tough world of trying to get investment, doing thorough R&D and
delivering a great product at a competitive price.
We came close but were let down by technical problems outside of our
control and had to close the company.
The ideas however have continued into products now being used by
other companies.
