Octane, Viper, Cobra are all the same units in different colours made by Good Sense in China.
they claim "serviceable by any dealer in USA" - we for one do not touch them as we unfortunately learnt the hard way. The customers in my market that have bought one of these private label brands all hate them and wish they never bought it....live and learn I guess.
