Is Viper considered a high quality company?
"Viper" is just a brand owned by "DEI".
DEI has been a major provider of car alarms for over a decade. I remember DEI alarms being very popular in the 90's.
To answer your question, I would say yes.
Headquartered in Southern California, DEI Holdings, Inc. is the parent company of some of the most respected brands in the consumer electronics industry. DEI Holdings is the largest designer and marketer in North America of premium home theater loudspeakers (sold under the Polk Audio® and Definitive Technology® brand names), and consumer-branded vehicle security and remote start systems (sold under Viper®, Clifford®, Python®, Autostart® and other brand names).
