They were packed good and work good on the job site ,overall good quality so far haven’t broke one yet even dropping from high places
I am a bail bonds and fugitive recovery agent. I bought these based on reviews. I wanted and needed new radio's for when my team go after fugitives. Once I got them, I field tested them in a large 2 story structure made of metal and cinder block. We tested them in all different ways....inside to outside, diagonal, upstairs to downstairs, etc. Passed with flying colors and more!
I brought these for my business, and they are great. Love the fact that they came with individual charges and are very clear.
Really great radio for the money. I have a Christmas Tree farm and I bought these for my employees and I to be able to coordinate parking and sales. They were always in range inside or out. Great calling features and security code blocks. The battery life is REALLY good. I used them without charging for 3 eight hour days and one was even left on over night. No problem. Very clear transmissions. I worked in law enforcement for 20 years and carried a portable daily. These had equally clear speakers. The instructions state they should be stored with the batteries discharged. I have closed for the season and after just charging all of the radios I had to leave them on to discharge before packing them up for the year. They have been sitting and turned on for 3 days and they still have battery life. Great deal for the money!
I work in a 41 story Bld under construction in downtown Dallas. Everyone on the job uses these. They travel thru the construction walls & concrete floors with no problems. The price was great. All of us use these to get elevator access. Thx,Judy
So far they work well for our purposes, works extremely well on 100 acre job site, have held up well in the equipment
Great for a team. They have a good distance for a big building.
This works great for our operations, most of my employees are on forklifts and having all of them with a radio makes shifts so much more productive. I work in a beverage manufacturing facility, with about 200,000 square feet- plus our trailer yard- and these radios have not disappointed.
Great product for the money very durable and easy to use I manage a 42,000 sqft store and my employees love using them.
We used these daily at work in a retail setting. They have been the best radios out of the 3 or 4 we have tried. They have lasted the longest. Easy to use. Charging dock is great.
I have a team of 40+ and we use these on forklifts to stay organized. The size is perfect and the ease is excellent.
