## Customer Reviews

### ⭐⭐⭐⭐⭐ Great price and indeed works
*by C***Y on April 21, 2025*

This sensor is indeed compatible with my Max XT2 meter. I have changed a few using these over the years and the quality and compatibility is good. Haven't had any codes or issues with the sensors yet. The price is what drew my attention to these and its quite a discount. I have trusted my life with this sensor in my meter and since and because I am typing this review, is proof that it works perfectly :-)
