Definitely worth the price on these. Can't beat them. Range is good all over the plant I work at. Ear piece is a must with these in a noisy environment because main speaker doesn't get very loud. Would definitely buy again, and recommend to anyone needing cost effective communication for their work area.
We need the devices for a large house with concrete walls in the event area. The parts are quite robust (I often drop the radio on concrete, slab floors or paving stones...). The performance ratio is absolutely right.
I bought these walkie talkies for hiking and camping, many campsites in remote corners of the UK have no signal. We did get good distance and my hiking group approves very much. Easy to set up and the battery life is great. The earpieces also fit the ear very well.
