A&D Medical LifeSource UB-512

The A&D Medical LifeSource UB-512 wrist blood pressure monitor receives a decent accuracy score in independent testing, although two other wrist models top it, including the best-reviewed Omron 7 Series BP652 wrist monitor (*Est. $70) . It has a 60-entry memory that stores morning and evening readings, along with irregular heartbeat detection. It also has and the ability to automatically calculate the average of consecutive readings.

Owners say they like the UB-512's portability, one of the perks of using a wrist monitor that's smaller and lighter than a comparable upper-arm cuff. Most users say it reads true and works quickly, but some report that the monitor gives erratic results if it isn't positioned correctly. Others say they wish it had a few more features, such as time-stamp recording and a larger memory. If a feature-rich monitor is your priority, the upper-arm Omron 10 Series BP785 (*Est. $80) costs a bit more but offers a wider range of features including a more expansive, time-stamped memory function.

The A&D Medical LifeSource UB-512 appears in a 2012 ConsumerReports.org roundup of blood pressure monitors. Amazon.com is the largest source of user reviews, but reviews for two other models are mixed in, so read carefully. Additional user reviews are available at Walgreens.com and Walmart.com.
