## Before you buy

- The listing is inconsistent about colour \(title says blue, details say yellow\), quantity/pack wording, and power \(rechargeable feature and 3.7 Volts conflict with a claim for two included AA batteries\). It also gives an unclear weight of 1204 Grams for the item and does not clearly confirm the battery or charging arrangement. Confirm these details in the selected listing before purchase. The waterproof and MIL-STD-810H statements are manufacturer claims, not independently verified here.

## In the box

- RB648 walkie talkie (Included): Explicit contents list names the radio but does not state a quantity.

## A good fit for

- Buyers seeking a pair of handheld radios with listed 16-channel selection.
- Users who value the listing's waterproof and toughness claims, after confirming the selected item details.

## Less suited to

- Buyers who need confirmed charging, battery type, colour or exact pack contents without checking the selected listing.

## Customer feedback

Customer feedback is positive about perceived build quality, functionality, range, clear sound, battery life and ease of use. One reported use was on jet skis offshore, and another described coverage across several kilometres. These are customer impressions rather than guaranteed range or endurance figures. They may matter to outdoor users, but the listing gives no verified range figure and its battery details are inconsistent.
- Positive themes: Customers report sturdy build, clear sound and ease of use.
- Positive themes: Feedback describes useful range and long battery life.

## Frequently asked questions

### How many channels are listed?
The product details list 16 channels. This does not by itself indicate simultaneous listening on multiple channels.
### Are the RB648 radios rechargeable?
The listing labels them rechargeable and gives a voltage, but also claims two included AA batteries. The battery and charging setup is unclear, so confirm it before buying.
### What colour and quantity should I expect?
The title refers to blue and uses unclear two-pack wording, while the details say yellow and list two packs. Check the selected listing for the actual colour and number of radios.
### Are they waterproof?
The details claim waterproofing and give an IP67 rating. These are listing claims and are not independently verified here.
