I highly recommend this navi r3 !!!

I especially like outdoor mountaineering, but one or more people deep in the mountains, this situation is actually very dangerous, very easy to get lost. Therefore, I bought navi r3 from aolon, which is specially designed for people who like outdoor sports. It has a high-strength glass panel, deep water resistance of ip68, and high-precision gps positioning function, which I really like. The most favorite is his built-in gps function, which is really very useful, although the mobile phone also has this function, but the battery life of the phone is very limited, but the navi r3 battery life of up to 15 days, there is no need to worry about running out of power and causing it to be unable to use. It's a good way to keep me safe
