Here's Elos' response ...
Thanks for using our products and contacting us. The angle on the illustrated pamphlet is ok but i know what you are describing that it is possible to "chop the drops", if you hold at an angle. The bottles used in the Elos kits are metered drops so it is best to get close to vertical or vertical for best results. Hope this helps and let me know if you have any other questions.
