Extruded Aluminium housing with plastic end caps. No heat sink on any parts inside. Runs hot ( CPU 55 when external temp = 15 degrees. Very stable signal. Low latency. Simple interface. Average CPU 15% RAM 48% Flash Memory 65% usage. Non socketed CPU RAM or Flash memory. Impressive GSM signal quality in an extremely weak signal area.

Functions as it should. Now I just need work to reimburse me

Because of its high temperature rating (up to 75degrees Celcius) I'm able to have this router operating inside my car even when it's hot outside. The ability to track the temperature remotely is also a useful feature

Excellent product that works well - thanks
