The receiver is one piece molded plastic ... no seams ... and sturdy ... the leads are heavy with molded battery charger type leads ... which is a nice touch
The remote has both on and off buttons (over a single toggle off/on) giving you more confidence that your sending an on or off signal. It also has a shade to cover the buttons to held keep out any contamination
Lastly ... when on, it has its own led indicator indicating so
I think it’s a great sturdy mature product ... we are using it to turn on a auxiliary tank pump for our snowcat / trail groomer
