Hi! I took your recommendation and ordered the only reasonably priced klene drop I could find on amazon: https://www.amazon.com/dp/B00JBWEHC0/ref=cm_sw_r_cp_apa_glc_fabc_KP0G0ZVX4ZWAQN66SMPZ

That doesnt appear to be specifically what you recommended, but it's at least that brand. Have you tried this before?
