Just got my Level 2 control solution and wow - next day delivery was a sweet surprise! The bottle stays perfectly moist inside, which is great for multiple uses.

Used it to throw a 'Glucose Monitor Party' (yes, that's a thing now) with my diabetic friends. We tested 5 machines and most showed consistent results except one that read 20-30 points higher - potentially dangerous for insulin dosing!

My own meter showed 116 against the strip's range of 94-126. The math nerd in me calculated it's reading about 6 points high at mid-range. Not bad, but good to know for accurate tracking.

Pro tip: These solutions are perfect for cleaning your lancet device too. Two birds, one stone!
