I manage a sugar cane farm in the Philippines and wanted a low-cost solution for field communications. My farm is 40 hectares in area and approximately 3 miles across at the farthest points. One half of the area is slightly hilly while the other half is flat land with a small residencial community. The radios work perfectly for my needs. Their range can accomodate the length of my farm on any given day maybe except for days of heavy rain. Of course our locations has the added benefit of hardly having any electronic signals to interfere with. They are easy to use especially with the simple selection of channels rather than matching specific frequencies. Another great advantage is the use of simple AAA batteries which are easy enough to procure here for replacement rather than a specific battery pack. The only drawback to the product is that it only comes with a 110v charger not a universal one to accomodate our local input of 220-240v. Therefore I have coupled the original chargers with step down transformers as well as bought local aftermarket power supplies to charge my units. On both occassions, our not-so-stable power grid is my suspect, of both power supply units to burn out and a few of the units themselves due to the sudden fluctuations rather than any poor quality of the product. But for the price and the effectivity of the product, this is now the second set I have bought because it is still well worth your money (even if I need to replace the units and chargers yearly due to our power fluctuations).

With no sub channels, these cannot be used with any other radios that use sub channels. Also, the PTT we use for our other radios don't work with these because these require a separate jack for listening and a separate jack for speaking. Other than these, they worked and would likely be good for simple family communication - but nothing serious.
