Sorry for the trouble. I have several ECA and Green Gain bottles in circulation that I refill from 500ml bulk bottles, so they have been in use and refilled again for months and have never clogged. That's not in any way to say it can't happen, obviously it happened to you, but I don't think it is widespread problem. ADA is very finicky about such things.
If the problem continues or if anyone else experiences this, send me back the bottle an unused portion and I will replace it for you.
I find the drop rate to be very precise, but preferences may vary. |
