I bought these for my Daughter, her Husband and 4 kids. They are always traveling, hiking, canoeing, caving,horseback riding, etc. and they have alot of land. It was perfect for them. Works great all product info is true.
Plug and play. Batteries last 10 hours for our events. Comes pre programmed with multiple channels. Recommend buying the box set with ear piece. I also bought the lapel mic. We love them.
Awesome radios. We own an event venue and it's surrounded by 22 1/2 acres mostly woods and the reception is clear as could be. All of our staff is equipped with these and they are a must have for any future events. We couldn't be happier. They came so quickly too, awesome deal.
In our school we couldn't find good radios until I bought these. They work great!!!
Bought these for neighborhood watch team. Very easy to use for all the team, older and younger, male and female. Crystal clear throughout the entire neighborhood which is approximately 1 1/2 square miles and heavily wooded. Great radios for our use.
These are great little walkie-talkies! I organize events and got like 15 of these in the past few months for my production team. They work within 4-6 mile range outside perfectly, and work even better in the large convention centers. Battery lives for 1,5 day of active use. Super easy to setup channels. The size is compact Overall super happy with them.
Bought these to use for stroke/turn judging at swim meets. The local swim organization uses the same model week in and week out and has had great success with them, so it was a no-brainer to choose these for my personal kit. I've seen the organization's radios dropped on the deck more than once and come out without an issue, so I feel like these are reasonably rugged for the price.
Great radios! Worked perfectly for the sporting events at my high school.
Bought these for a cruise. I didn’t want to spend extra money on the WiFi package. And these worked great! Glad I got them and we were able to use them everywhere.
We use these at a school, inside and outside. Extremely clear and audible.
We use these radios twice a week from 7 AM till 3:30 PM so far so good on the weekends. I will charge them every week just to not have any issues with a dead battery. I havent test the battery life but for 2 days, works great
We use these in an animal shelter and have been very happy with the performance.
This radio makes around the farm communication easy.
Great battery life, range and sound quality.
Really like the beating these can take. My staff are not gentle with these and so far we have had no breakages unlike others we have tried in the past.
This is a great product for a team to have great communication when cell phone signal is not the best. I have use this several times on different types of jobs. They are rugged and hold up well. I also have use these on family vacations and they work great. The range is amazing and I have even allowed my children to use these around the yard or in the neighborhood so I can keep and communications with them when they are running around the neighborhood sound quality is great. Was a good value for the money.
Believe it or not we bought these for our family, not a job site. We have such a large family that it is important to us to have contact on our farm no matter who is where. These walkie talkies are very easy to use, even for our younger children. They are very durable. My son is really rough on toys and devices, but these are still working properly even though they have been dropped a number of times. Our voices are clear on them and they cover as far as we need them to on our 5 acres, so I would say they are great on distance too. Great buy!!
This walkie-talkie set is great when we have a team on location. Each one is sturdy, and these feel weather-sealed. The transmission range works over any property where we have used them, and the signal is crisp and clear. The single charging base makes them easy and convenient to charge.
I like having the PTT button on both the side and front, allowing the user to decide how to use it. Belt clip is screwed on, not a flimsy plastic connection prone to breaking. High power internal battery allowed constant use for 3 hours, and the battery charge icon still says it’s fully charged. The battery charging base is easy to charge and store the unused radios. USB-C is easy to connect if charging w/o the base, unlike other brands that use mini-usb (which require proper orientation, which makes them harder to connect). Sound is clear and the volume is controlled by an easy to find rotary knob (allowing volume changes while listening), not up/down buttons, which require you to look at the radio face to change. Accessories are limited, i.e., no wired PTT mic/speaker if you wanted the radio in a pocket or over the shoulder holder.
I bought these to communicate with my fishing buddy while we are fishing the flats. I can't attest to how far exactly these would work but being 1 1/2 miles apart, they worked just fine. there were no obstructions or hills in the way - justa straight line of sight. The waterproof design was very important to me since they are used while walking in water. One was dropped in the salt water and was rinsed with fresh water at the end of the day and continued to work perfectly. For my use, they worked great.
Great radios, very sturdy, water resistant, good volume, easy to use. 2 watts of power provides plently of range for UHF frequencies.
Fast Shipping!I bought these radios for my team members in our building, and they’ve been a huge hit! The radios arrived quickly, and the team loves them. They are easy to use, reliable, and have great range, which makes communication throughout the office seamless. The sound quality is clear, and the battery life is impressive. These radios have definitely improved our team's efficiency. Highly recommended for any workplace that needs quick, reliable communication tools!
As easy to use as advertized. Intuitive and responsive functions. Charges quickly. Range hard to gauge, but expected to be adequate based upon local usage.
I bought these for my workplace that is full of dust and water. My guys drop them on concrete daily, they have been dropped in water etc and are still going strong!
