Pros The greatest advantage of the CLP1040 is its small size. It measures at just 3.5 x 2 x 0.75 inches with a weight of 2.38 ounces.
The CLP1040 has a magnet clip mount that lets you attach it anywhere on your clothing.
Cons Power output is only 1 watt so range may be a factor for some installations.
There is no internal speaker so the user must wear a headset.
Summary The Motorola CLP1040 is an excellent choice for applications where you need a small, light-weight two-way radio that is easy to use and comfortable to wear, and your team members don't mind wearing a headset all day. As long as you don't need to transmit great distances, or you are willing to put in a repeater system, this radio should work well for you.
