Exelente cálida están muy bonitos
These Retevis RB48 walkie talkie are great and the long range is true. Through five Bronx city blocks with tall buildings, I could still communicate with my wife. I brought the radios so that when we are at the mall we can keep in touch. Waterproof and rugged, the radios do their job and do it well. I recommend these walkie talkies.
Seem to work good.
Battery last a long time, built extremely well and can take a beating. The dual charger is great.The price is great for the quality, plus other radios are priced higher with less.
Great quality—have been completely submerged in water and floated and continued to work fine…great range with clarity
So far so good real clear sound no static at all' very satisfied with product. I recommend it if you like camping even at work for myself I'm a farm worker so they're helping me a lots 👍
Great value for money. Clear signal across a few miles of open terrain. Battery life was excellent. Switching channels was easy and allowed contact with other parties on different channels. Very durable thus far.
Good radios
These are pretty good. All of these free bands are spotty reception anywhere residential but they work pretty good out in the open space. I got these on sale so that was a great deal, full price, I would hold off till the next sale.
These things work well The range is incredible The clarity perfect
Seems to work well (tested locally with a one block radius, true test comes in the woods while camping soon)but it would have been nice to receive instructions with it.
Very good radios use them for flagging great sound quality and distance. And they are waterproof. Also love that they are rechargeable
Works as described.
I bought these radios to use in the Boundary Waters Canoe Area camping. I was able to pick up the weather broadcast channel on them from inside the wilderness. The reception is only about 1/3 of a mile through thick woods but about a mile on open water. I did drop one in the water and it was not damaged and still worked great. We also used these on a cruise ship. The reception of the cruise ship would only work if both sides were outside the walls of the ship or only separated by a few floors/walls. The battery life lasts all day and at the end of the day still had about 70% battery. I would recommend these radios to anyone who has realistic expectations about their reception capabilities.
Estos radios me gustaron mucho son buenos prácticos y economicos
Easy set up, strong transceiver, and pretty indestructible. I use it when I'm "down the road" mowing, so I can communicate with my wife.
The device is resistant, good quality, good range.
Work great! Hubby used these on an atv trip. Worked great. Eazy enough my 8 year old sons had no problem understanding.Also kids used them on a road trip keeping in touch with other cars in a caravan, worked well.
Worked well for our simple usage. Easy to use. Battery lasted a long time - we didn't talk a lot and the batteries on all 6 units were still at all bars after 4 to 5 hours. Liked charger and belt clips. Didn't use long distance - only 1/4 to 1/2 mile, but steep terrain and not always line of sight. At times think we were at the edge of its capabilities. Good volume and clarity.
I haven't really put these to a proper test, but they seem solidly built, have great ergonomics, and are easy to set up and use.I did a quick test of the range by picking a spot exactly .5 miles away that is separated by a moderate ridge (about 40' in elevation above the spot where the other radio was being used) and also 200 yards of thick hardwoods. The signal had a good bit of static at the .5 mile spot but I was still able to effectively communicate, even with all of the obstacles in the way. If it were open ground with no obstructions I'm sure I could easily get a clear signal at 3-4x that distance.So far I'm impressed, and will update after I use them in the field during the next fall/winter hunting season.
