WOW... this thread is starting to melt down! Funny thing is that this happens a lot in the car forums that I frequent when it comes to chinese made things. I guess it also happens in cell phone forums as well! Well, I have been using ebay cases, batteries, and chargers both car and home for all the phones I have ever owned. I have NEVER had a problem with any of these items that I have purchased. Oh , and to the guy that posted that the cell phone will blow up in our faces? Are you serious bro? If that is the case then we are all walking around with ticking time bombs up to our ears!!! If you want to spend 40-50 bucks on batteries, cases, and chargers then by all means but don't dissuade people who want to save a few bucks on something.
Competition is good. However if people (like myself) go out of the way to buy this battery and then post their results then why crap on the item or them? I was skeptical at first when I bought this battery but so far it has been great and hasn't flinched in terms of performance once. If you like spending a premium on brand name stuff then by all means go for it. If you want to save a little dough for something that will perform just as good or a little better then that is your choice too. If you are terrified about your phone grenading on you when you are calling home to your momma, when one of those pictures even show an oem Samsung battery, then you should stick to land lines and pay phones...
Seriously people...
