I've used Square trade for a few years, I haven't had to actually file any claims yet though. I found them via Apple forums when I bought my first Iphone, at the time no one offered a decent plan for Iphonees and they covered them including full immersion in water.
Since then I have 2 IPADS, 2 IPHONE, 1 Home Theater and now my new Nikon D7000 camera kit covered with them. If you get a warranty and decide you don't want it or sell an item you can cancel and get a refund that is prorated.
I did have a suspected issue with my phone and when I called they were willing to work with me to have it repaired local instead of shipping.
Last March I purchased a Nikon D7100 from B&H along a
three-year Square Trade warranty. The following month (April)
I was shooting a festival in Phila. I had my D7100 attached to
a Sun Sniper Pro camera strap (not recommended)where it
detached itself and fell to the ground cracking the LED
screen. That day I called Square Trade and filed the claim.
Really great customer service experience in so much that I
felt that I wasn't chasing down some
"maybe-they'll-go-away" rebate claim.
They were unable to repair the camera in the allotted 5-day
window and refunded the cost of the warranty. Since this was a
fairly new model my thinking that Nikon was looking to put LED
screens into whole production camera's rather than replacment
parts as a prority. The camera left Square Trade's service
partner and was sent back to Nikon for repair and then I was
notified that the camera was on a parts hold and they could
not determine when that part would be in. I discussed this
with the Square Trade cust. ser. reps and they put in for a
full reimbursement for a new D7100 which I got within a week
of that decision. They were so easy to deal with and they got
back to you when they said they would.
Based on that experience I won't buy a lens or body of major
value without a Square Trade warranty. They do exactly as they
claim they will do in the ads and on their web site. Bad stuff
happens some times. These guys are worth the extra bucks for
the recovery process.
I wish you good shooting with 800! Last summer I purchased a Nikon 24-70 mm lens, again with a Square Trade warranty in tow. Won't leave home without one and I hope I never have a reason to use them. But I'm really glad they have my back.
