A step backwards
The older version of this device was smaller, and had a longer battery life. The current version is large, awkward, and has two antennas, which are plastic and easy to break. The new one has more features, none of which I find useful, but you might. The biggest bummer is the battery life - I go through three batteries in a day. Don’t upgrade, but buy version two if you really need it. The company has excellent customer service.
