What to know before buying
Listing details to confirm
The listing gives 2 miles as the maximum talking range, while its feature copy gives a terrain-dependent range of 0.5–2 miles. Actual coverage depends on terrain and conditions. Battery life is stated as up to 23 hours at 90% standby, 5% talk and 5% listen, not as continuous talking time. The feature text compares it with the RB48, while the specification table gives the 23-hour figure without that condition. The listing also calls water resistance Waterproof and separately claims an IP67 rating. Check the exact rating and selected configuration before relying on it. NOAA/VOX are described as options for customizable keys, not unconditional default functions.

The supplied evidence contains aggregate star ratings but no customer comment summary. Those ratings are somewhat positive overall, with a smaller one-star share and some three-star ratings, but they do not explain customers' experiences or establish performance. They cannot confirm the claimed range, battery life, noise reduction or durability.
Frequently asked questions
How many radios are in this set?
The listed contents specify four RB48A radios and four speaker microphones.
What range should I expect?
The specifications list a maximum of 2 miles, while feature text gives 0.5–2 miles depending on terrain and conditions. Treat these as listing claims, not a guaranteed distance.
How is the 23-hour battery figure qualified?
The listing gives up to 23 hours at 90% standby, 5% talk and 5% listen, so it is not a continuous-use runtime.
Are NOAA and VOX available by default?
The listing says side-key functions can be customized through CPS and gives NOAA/VOX as examples. It does not establish them as default functions.
