Excellent quality and range. We are currently using it in a 250k sq ft warehouse with no issues.
We live on a mountain with no cell service. When my kiddos ride bikes in the neighborhood or go into the woods they carry these so we can communicate. Works well even with all the hills and valleys. They are sturdy and durable. I wish they came with a neck strap though.
We use these to help my elderly mom stay connected throughout the house and on our one acre of land. They'll even tell you to charge your battery when it's low. We turned on a few on the charging base and they have been working without issue. The only thing is it would be better if the knob was more damped.
