This monitor was used for one month for 15 days. I was able to get pregnant and learn my cycle quickly, so I am selling it. It has never been dropped and was purchased January 2024. You can buy a new clip to fit any iPhone, but this one comes with an 11 Pro Max clip. It comes with 2 sealed boxes of strips and 2 extras. All box comments, including the manuals and original boxes are included. Everything originally cost me over 230 dollars for new strips and the monitor. Offers accepted.
