Getting two new VZW 5s phones here. IF we go with anything it will probably be Applecare +.
People have to make their own assessments of risk & probability but TEC/Asurion seems like the LEAST bang for the most bucks to this consumer. Also, they seem to screw their customers over on a regular basis; many of the complaints on VZW's FB page seem to be about TEC/Asurion & the poor quality of refurbished phones they provide as replacements, even for brand new phones that quit working.
According to my research from May 2013, coverage for 2 iPhones for 2 years comes at the following prices with these vendors:
Applecare+ = $200 (ADH only, 2 claims over 2 years, $79 to replace damaged phone, $0 for warranty replacement, repairs to existing iphone may be done in-store. New or Apple refurb phone replacements)
Square Trade = $200 (ADH only, Max Total Claim = $599. $599 reduces as claims are submitted until $0 left)
Ensquared = $260 (ADH + LS, 3 claims x $1000 over 2 years, $179 deductible per claim, replacement phones are "mostly new")
TEC/Asurion through VZW = $480 (ADH + LS, Max Total Claims =$3000 with 2 x Separate $1500 claims, $199 deductible, replacement phones are refurbs)
[Please note that most or all of the above information is current to May 2013 - do your own research for what's available NOW.]
Finally, FWIW, Consumer Reports advises against purchasing extended warranties, calling them rip-offs. They advise hanging on to your old working phone so it can be activated in the event your new one doesn't work or goes missing somehow.
