Good product. Received product 29 Apr 26. Expiry date labeled 2028 10 14. Hopefully still good after that date. Will need to do a lot of testing to use all product before expiry date. Downside -- Shipping cost of $18.86 for item is costly. Would be nice if cheaper shipping option available. Only 3.5 stars for reasons above.

Thank you for review.  If stores properly per Stability document, strips can be used past the posted expiry of the bottle you have (2.5 years remaining).
