Scot M Barker –
Solid great battery life
The Retevis RB48 is built like a tank—clear audio, strong range, and excellent battery life. Easy to use, even with gloves on, and tough enough for work or outdoor adventures. Reliable, rugged, and worth it!I don’t think any walkie-talkie has the range it advertises inside of the city, so keep that in mind. We use ours a lot with the children, riding their bikes around the neighborhoods or within half a mile to a mile away and that worked great. Again, consider the region in which you’re planning to use these.

Clear sound
These are a great deal. They work well, range is sufficient for my needs. We added the headsets and it makes for a great tool. Sound is clear, holds a charge well.

Worked great, even in the rain.
August 2025, I bought a 4 pack of these for use by me and the other parking lot attendants at a big two-day church fair. The furthest two people were separated by about 200 yards. The walkee-talkees worked great all day. Held a charge for 12+ hours with no problem. I recharged them the first night and used them again the second day. Same thing. In fact, they got heavily rained on the second day, and still worked like a charm. (If you look carefully at the photo, you can see the yellow units in our hands.)

Jobsite usage
Bought these for a jobsite when we didn’t have access to CB radios for our equipment. Worked extremely well for our intended use. Small and compact for easy stow away and clear audio made for no miscommunication

Solid Radio
Figured this is the type of review some people are looking for with commercial construction I bought these 3 weeks ago while supervising on a scrap ship got 4 of them for about $130 and they have a good audio quality and respectable range. Through houses testing in my neighborhood the audio quality wasn’t great about 2 miles out at the store however on a job site It does what I need. I work 12hr shifts and it doesn’t appear to go below 3/4 battery however I charge daily so couldn’t give a full concept of repetitive use battery life over a few days. I did however accidentally leave one on over the weekend after 12hrs on Friday and on Tuesday it was down to 1 bar. It rained pretty heavy this last Friday on the ship where the entire day it was exposed to rain and had no issues. For about $35 a radio I am extremely happy. It has an audio jack, usb charging port with waterproof caps and the magnetic charging station which usb cable splits into 2 usbc so you only need 1 outlet port for charging 4 radios. 22 stations with 120 sub stations per to seperate work groups and stay off other people’s channels. They aren’t overly bulky and their clips seem sturdy. I do kinda wish it had the knob for switching stations quicker as I sometimes put crane operators on their own station to avoid confusion but this is definitely a solid quality for the price.

Nice and sturdy!
We’ve had these for a couple months now and they get used every day. They have been a good purchase for us and I’m happy to say they are pretty tough little walkie talkies! We use them every day with our teenage kids around the farm and all of the walkie talkies are still in excellent condition.From a technical standpoint I like that they will buzz to get your attention when you haven’t used them in a certain period of time. I also like that they light up red or blue depending on who is using it because it can get confusing with 4 people using them at the same time. With that said, it’s sometimes hard to coordinate because we sometimes talk over each other but that’s more of a user error than the walkie talkies. It would be nice if there was a way to prevent the talking-over issue but I think that’s just a walkie talkie thing in general and I’m not aware of any brands that would prevent this issue.Overall these have been pretty great and are a lot better than some other brands we’ve gotten through the years. The antennae has stayed on nice and sturdy with this brand (Retevis) but we quickly lost and broke the antennae with the Dewalt brand. These Retevis walkie talkies stay charged for many hours even though we leave them on all day every day and only turn them off to charge at night. There are plenty of channel options to choose from to avoid neighbors, and we can hear each other very easily across 40-60 acres with some tree coverage. Definitely would buy these again!

Handheld radios.
Great range. 1.5 miles and clear. Light weight easy to handle.
Isabell Holland –
Range
These do not reach as far as listed in the description. They reach no more than half a mile. Other than that they work well.

buen alcance y resistencia para uso rudo

Se configura sin dificultad y, aunque lo he probado poco, tiene buen alcance en espacios abiertos. Ocasionalmente los ocupo en zonas urbanas para algunos trabajos; sin embargo, aún no los pruebo en esas zonas. Buen producto inicialmente.
