** T721 Digital Non-Programmable Thermostat** The T721 Digital Non-Programmable Thermostat has garnered mixed reviews from customers, showcasing both its ease of use and some challenges with visibility. Many users appreciate the straightforward installation process, noting that it pairs well with older heat pump systems, such as the RHEEM models, making it an attractive option for those looking to replace outdated thermostats without complex programming requirements. Customers have lauded its effectiveness, especially in heating modes, highlighting a successful switch from malfunctioning units to a reliable heating solution. However, one recurring point of criticism is the readability of the display.

Overall, the T721 serves well for basic heating needs and convenient operation, but potential buyers should be aware of the visibility issues that could affect usability, particularly for individuals with vision problems. **
