• Reseller for Greentek Sensors products are very expensive

• We ask ourselves whether these caps are worth this much. Or if it is better to build such caps ourselves

• They miss some features we miss

• Why not to build it ourselves?

• They do not look as if they where the latest high-tech products

• They are very rarely used in papers

• They are hardly developed further
