Woot's warranty is 21 days, period. Can you live with that?
We bought a "refurbished" Sony mirrorless camera. The lens (the expensive part) failed (camera won't recognize it) in 80 days during our European vacation. Camera wasn't in that good of condition when received anyway - not refurbished, just worn, with a dirty sensor.
Amazon owns Woot; I like Amazon, but now I think Woot is just how Amazon dumps their (easy) returns. I would have been better off buying new at retail locally, with a real warranty. Woot promotes itself as being cool, funny, and hip, but really it's just a ripoff. I recommend you stay away; I know I am.
