I think this is the key... does Cobra actually design and manufacture these boosters, or do they simply rebrand another manufacturer's product? When I was looking for my booster I researched an AC Delco model and found that it was sold under at least two other names as well. Cobra does have a positive reputation for its core product line of radios, so it makes sense that they might try to diversify their product line by putting their logo on other manufacturer's products (Honda Passport anyone?) until they could start producing something on their own.
