Query: KX-TG5777SK - great phone, poor seller

I purchased the KX-TG5777SK on sale for a GREAT price, but I wasn't aware until I opened the box that it was apparently a refurbished unit.The bad: stickers with unremovable goo on the phones, paint already scratched off the somewhat-nasty looking finish, data not cleared off the phones, "ghost" handsets still registered to the base unit. Unlike what the Amazon description states, this has only a 90-day warranty according to the invoice, manual and stickers plastered on the phones.The good: at least the batteries and accessories are new, the phones work AMAZINGLY well, packed with features, I was able to clear the phones and re-register them with the base unit fairly easily, set-up was totally easy, and the little screens look amazing. I haven't used them for very long, but so far performance is excellent.
