The advantages to Taylor are the acid demand tests and the box itself.
That's an interesting comment about the kit boxes. Sorry for the small pics but the Taylor K-2006 is about 4x5x9 with the reagents upright and the TF-100 is about 14x11x2 with the reagents laying down flat. (180 cubic inches vs. 300 cubic inches)
In just about equal numbers, we get this....
1. "I just love the way the TF-100 reagents are laid out....so easy to see and use"
2. "I just don't like the reagents laid out like the TF-100. Can't you make that kit so it is compact and upright like the K-2006?"
Yikes! What to do?
