Specs: Frequency: 406-470MHz Frequency Range: UHF Voltage: 3.7v Channels: 16 RF Power: 2W Model: HTD-826 (Reference seller's manual for additional functions, operation, etc.) Bought these walkie talkies for my wife and I to use when we go car camping. Bought an extra set in case we ever had friends or family with us. We hardly used them, mostly used when we needed spotting when driving through difficult terrain. They can be very handy or simply to have fun with. Though it may not look it, this radio is way more advanced than the toy ones that go for the same price. The price is for all four, will sell one set (2) of $25.
