Just a happy suggestion on a Thursday morning - if you are thinking about buying a test kit, go for the XL option! I am SO thankful I did because this morning I used the last of my DPD Powder from the original kit (I've been testing heavily due to an AA treatment). If you go XL, you can keep testing without skipping a beat! Of course, now I need to order replacement supplies... but that's just the cost of doing business!
Have a great day, ALL.
