I feel really really really bad about throwing away these cartridges when they seem like they are still in good shape but are empty. I am sure the bite valve has some sort of limited life, but it would be nice to be able to buy resin in a bulk package (think boxed wine) where we can reduce waste and recycle the majority of the packaging. This should reduce resin cost too which I am sure your higher volume users would appreciate. I am sure they would be willing to pay for a more durable reusable cartridge system also if that is why this doesn’t happen.
Not a bad idea at all. Maybe some one is listening as they don’t seem to listen that much. [grin]
