Checkers are top-notch. New version with powder as second reagent: finally correct results. On the other hand, the checker is not programmed for the 3-minute wait before reading, and there's no brochure on this reagent kit indicating the test procedure. You'll have to find it on the Net. So, great progress, but poor management of the transition from v1 to v2. (Translated review)
