No problems, I just wanted to replace the battery as the one which came with the system, was draining way too fast.
Very easy to be replaced as long as you do it slowly and careful.
My advice is always people should by products from you:
1. Those products are original;
2. At a very reasonable price;
3. Extremely fast shipping;
4. Reliable source.
I will always by products from you. This is my second time I purchased items from ifixit.com and I have a wonderful experience.
