Review on 📱 Silicone Protective Cover for Garmin GPSMAP 66i – Handheld GPS Accessories by TUSITA by David Dugas

I didn't get a case for my '64 and over time the thin rubber coating has worn away. Ugly and slippery. (In addition, the loss of the coating also exposed a tiny hole inside the device where a corner of the case was chipped off during manufacture. The device would not survive if dropped in water.) Hopefully this case will prevent what happens on the 66i. My grip on the device has also improved with the case.
