I did a search on this topic and found that the last thread was 5 years ago. Has anyone had experience with these? I think the standard model is the one developed by Gene Davis and marketed by Bulzeyepro.com, and there may have been some developments and improvements in these devices since 2011, when the last thread appeared here. Evidently at one time (maybe around 2009), they were being imported for sale in Canada. Anyone know whether this is still true?
