I read the previous view before ordering the battery from these folks. I knew the risks but figured the possibility of battery failure was slim. Well, I was wrong. Like the others, the color does NOT match the Mac, it does not quite fit properly, but, hey, at $29, I was willing to chance it. Well, I got my money's worth. First, it would not charge at all. Then, after many restarts on my computer, and removals and reinstallation of the battery, I got it to begin charging where it charged only to 67% capacity. Having read the previous similar problems, I drained it down to 0% and recharged. It recharged to 86% this time, and continued to increase after each drain a few percentage points until it finally hit 100%. Then it broke. Just stopped working. Dead. Electricking, which could be interpreted as Electric King or, elec tricking ( I prefer the latter) , made me pay for shipping it back rather than have a prepaid return label (as other catalog companies do, such as LL Bean, or Lands End), wouldn't send a replacement first, also as others do (like Apple or Verizon) where I would then send the defective product back in the prepaid box. I had to get a box, mail it at the post office, and then email them, where they promised to send a replacement AFTER I send them the tracking number (which means I had to pay extra to get it tracked). Okay, done. I now get an email that says, rather than sending a replacement, as promised, they promise (again) to send a replacement when they get back to work, whenever that is. We'll see. It has now been 7 days without a battery, and my MacBook has become a small desktop computer tethered to my desk, and dies when my wife "borrows" my AC adapter, or I kick the cord and it disconnects. Lots of fun. If the replacement ever arrives here, I'll of course pray it works better. If it doesn't, I'll buy another real replacement from Apple for $129. Amazon can't possibly control the quality of all the vendors it uses. Now u know why Steve Jobs thought end-to-end product control was so important. Also, my wife got sent the wrong textbook for our daughter thru amazon, could not get relief from Amazon or the Vendor, who refused to refund her money when she had the tamarity to write a review telling of her experience. There is a major difference between buying directly from Amazon as the vendor, and buying from some "elec tricking" company thru Amazon. "Caveat Emptor" (Buyer Beware).
