I purchased it to program Harley. Pretty nice
Color: Silver, Memory Storage Capacity: 128 GB, Set name: Wi-Fi + Cellular
I've never had an Apple product before, the charging is slow, I love it because it's very light and durable I got it on sale So the value is very good. It's very thin also which I do like that and the collars are very bright and clear... I did drop it but from a low distance in the durability is great. Never damaged it a bit
