These work well with the Extech 445580
They've been durable too. Have been using them for a few months now, and the components haven't deteriorated any.

Horrible.
Doesnt work. I purchased the bottles ( that should have come with the meter) to calibrate a newly purchased extech non-functioning meter. It’s did not calibrate. Lol. I am returning all of the trash I purchased.
