FS/FT Hagen Master Test Kit

[nate_m]

I have had the kit for over 1 yr. I had never realized that they had a shelf life. Wish I had known that before it was purchased. When I look inside of each booklet it says best results in first year after opening. The reagents do not come sealed so the life of these kits is really only good for one year after manufacturing, not after opening. Considering stores don't flip these kits very often, the majority of these kits are likely useless when purchased. Oh well.
