As someone who has brought multiple "open box" items from Bestbuy i can say yes you can trust them. The battery maybe toast but it should be good.

Open Box Excellent does not mean all items are included. Their incompetent staff does not check to make sure all items are included.

Just purchased an “open box” Mac Mini in “good condition”. Brought it home and before braking the tape seal checked the serial number on the receipt against Apple database. This Mac was purchased almost 2 years ago and is simply used, not “open box” with no warranty whatsoever. Looks like inside scam to me.

I love buying open box from Best Buy. I just add geek squad protection for 2 or 5 years, b/c often there's no warranty when open box. If that's correct, buy the protection and you're good to go.

Don't necessarily believe anything about Best Buy’s “open box” items. I purchased a computer as Open box - excellent, which Best Buy tells me should include all documentstion, original packaging, full warranty, etc. Upon receipt my purchase came in bubble wrap, caps missing from the keyboard and no documentation. I attempted to get some assistance from Best Buy customer service for a replacement keyboard, but could never reach anyone who could offer any assistance, and the promises that ‘someone’ would get back with me within 72 hours was another lie from Best Buy - the most appalling thing however, when attempted to register ownership for warranty purposes, the manufacturer advised me that there was only 4 months remaining on the initial 12 month warranty. Best Buy is willing used merchandise and fail to advise their customers - don't buy anything from these crooks.
