Superb imo
I had my iPhone 4 (best phone ever at the time) for 3 years and dropped it down the bog.
Replaced it with the SE.
Same size
Same weight
But 10 times faster and a lot more storage.
You won't be dissapointed.
Have one of these as my work phone and an iPhone 6 as my personal phone. The se is a great handset which I sometimes prefer owing to the slightly smaller size.
The missus has one, she wasn't interested in the larger 6 as she'd had the 5S for a couple of years. As mentioned above, does all the things the 6 does and is the size of the 5.
