Customer Review: Poor range and unreliable; expensive batteries
I have owned five of these phones (each purchased with an extra battery) for a year and can not recommend them, for these reasons: 1. Line of sight range was only ~1.5km, not the 8 km claimed. This is under ideal conditions over a stretch of remote beach. 2. They are quite heavy and run *very* hot--are uncomfortable to use. 3. Seven of the ten batteries have already failed, suggesting that the charger design is no good. New batt's are $50 each! In the same period under the same conditions my Panasonic Multitalk-8 system has been flawless, and those phones cost half as much, in fact just a bit more for the whole phone than the Engenius *batteries*.
Customer Review: Nothing Comparable
I have had an Engenius phone and base unit for over 3 years. It has always worked and continues to work despite my best efforts to destroy it. It still uses the same battery it came with and works over 1 mile from my house inside my vehicle. I bought the phone because I wanted to have access to my home number at the neighborhood park, swimming pool etc. and in areas where our cell phones do not work well. Oh, I did leave it outside all night during a thunderstorm several years back. I found it when I backed out and ran over it with my truck. I took out the battery and dried it out for a few days and it still works. Nobody can guarantee that kind of performance but for once I got something that works as advertised.
