I just recieved my Rhino Hard Case for my X3i today and so far it's one of the best cases I have come across for my Ax. I do agree with the comments about the antenna not being we enough protected but that is a minor (unless I drop it) complaint about the case.
Good review though, the points made just re-enforced my choice of case.
Just a comment on the price, Rhino wanted $32 US (as indicated in the review) but I was able to get it NIB off of ebay for $23 US + S&H so anyone interested might want to check there first.
