The Uniden GMR1635-2 is a terrific alternative to a toy walkie-talkie, and a great way for parents to keep in contact with their children while they play in the neighborhood. However, compared to a higher-end two-way radio, their range is extremely limited and their features extremely basic. Also, many users say they go through batteries at an alarming rate.
Close range only. These inexpensive two-way radios have a claimed maximum range of 16 miles, about half that of pricier models like the Best Reviewed Midland GXT1000VP4 (Est. $55 per pair) . However, their actual range, according to owners, is a great deal shorter than that. A couple of users report getting a range of 1 to 2 miles in a suburban area, which is actually typical for this kind of radio, but most say that even half a mile is a stretch. At close range, however, the radios provide reasonably clear and static-free sound.
Bare bones. These ultra-basic walkie-talkies don't offer any of the features found on most higher-end models. There's no weather radio, no voice activation and no vibration alert. While they can operate on all 22 Family Radio Service (FRS) and General Mobile Radio Service (GMRS) channels, they don't include any privacy codes, so those 22 basic channels are all you get. They also take three AAA batteries each rather than using a built-in rechargeable battery. However, some owners find this to be a plus, as they can switch out batteries in an instant rather than waiting for them to recharge.
Burns through batteries. We did not see any significant durability complaints about the Uniden GMR1635-2. Battery life, however, is a different story. While a few users say that their batteries lasted up to a month with occasional use, far more owners complain that they had to change out the batteries after a day, a few hours, or even as little as 10 minutes. Using rechargeable batteries helps keep the cost down, but the frequent battery changes are still a hassle.
About 300 owners at Amazon.com give the Uniden GMR1635-2 an overall rating of 4 stars out of 5. Most owners are parents who say this basic walkie-talkie set is great for kids, offering clear sound and decent, although limited, range. Their biggest complaint is that the units "chew through batteries."
