I just received a new borate test kit that is drop based. It's cheap, the instructions are easy and I'm guessing it's more accurate than a strip (I've never used a strip, that's why I'm guessing). The kit utilizes some of the reagents one would already have in any kit comparable to something like a K2006.

I dont know if I can post the link or not - mods can you let me know, thanks.

I was also trying to contact Waterbear specifically about this kit to get his opinion (I think he was an early borate adopter if I recall correctly), but don't have the capability to private message. Maybe he can contact me if he reads this.
