Now that I've finally gotten this device to work, I'd say that it's pretty good. Getting to this point, however, was no fun and took weeks. Some of the buttons on the back of the monitor don't work that well, some not at all. Several correspondence exchanges with the company finally resolved a series of issues keeping it less than operational. The issues included getting an obsolete "manual" with the original unit, getting a slightly updated one that still didn't handle the problems, and finally getting the real solution via email, which should have been an integral part of the manual itself but was nowhere to be found in either. The first few responses from the company simply quoted the manual, which was no help at all. As noted, however, after several exchanges, the issues were finally resolved. You decide if you think 3 weeks of back and forth is worth it.
