I just wanted to mention I am on my second refurb'd Sansa Clip+ 4gb from Newegg. The first one held a 4-5 hour charge, tops (the advertise 15 hrs). The second one does not recognize microSD cards. This is obviously unacceptable.
I brought up the fact that the refurbs have bad reviews in this thread before I bought it, but was pretty much blown off, with stuff such as "only people with bad experiences write reviews", or "its fine I have a lot of refurb products", etc. I responded that newegg usually has pretty fair reviews, but that fell on deaf ears.
Anyway, I just RMA'd this again, they gave me a refund, which is cool. I will buy a non-refurb, its a great device. I would *highly* recommend that people do not buy the refurb Sansa Clip+'s, and spend the extra 8 bucks for a non-refurb. I would have happily done the same, but for some reason the first time I was buying they were above 40 bucks, which seemed to be an anomaly, but I didnt want to wait.
The Clip is picky about microSD cards. I bought a Kingston that it didn't like, then replaced it with a SanDisk that worked great.
