Iphone 4 + lifeproof case price?

I might e buying a iphone 4 with a lifeproof case, all in good condition, for $225.is this good deal?

Added (1). It isn't laggy, and he doesn't have any problems or anything, and its about a year and a 1/2 old

It sort of depends on the REAL condition of each.

What kind memory on the iPhone? How old is it? My husband has a 4 that is starting to have problems just because it was purchased on the release date. They truly do age.

I have a friend with a 4 that is having problems with the new iOS and the phone is only 3 months old… But no other problems, whereas my 4s isn't having problems with the update, So there's that too.
Also, Apple will probably stop support for the 4 soon.

I wouldn't trust a life proof without doing the test that the manufacturer tells you to do before using it on my phone (close it with a little piece of paper (NO PHONE) inside for 2 hours in a few inches of water). That said, I trust my own life proof enough to use it as a water-RESISTANT case but not enough to get it seriously wet.

Also, the size of the hard drive on the phone has a LOT to do with its worth.

I'll be here for 20-30 mins or so if you have more info to give me, though!
