Reach79's drop-proof black covers fit over the 6 or 6+, and are specifically designed to maximize the signal strength from cell towers, something Apple still seems to struggle with despite having made them for eight years now. Each case is fitted with its own large gold-plated antenna, precisely engineered to direct the energy from the phone's internal antenna onto itself, thus expanding the physical coverage area by over 100%.
To prove they actually work, Reach conducted tests in a shielded anechoic chamber, with the phone placed in a hand and held up to an ear, and found that they're capable of improving signal strength five times higher than the average. Can't argue with science, man.
