Wink basal body thermometer by Kindara. Long discontinued. I loved using this for years for natural family planning and have been hoarding it selfishly since finding out they no longer make them… but am finally ready to pass it along to the next owner! Still works perfectly with the app and reads temperature accurately. Only flaw is that one of the small black clips inside the main bogey broke off so the top comes off easier but it works flawlessly. Does not come with the box but I will provide a charging cable. Thermometer has been cleaned and the tip sanitized.
