On first day using it, after charging, laptop dies when it hits 45% battery. Pretty weird, so I reset the SMC because the watermark might be off. Doesn't fix it. I notice several gestures on trackpad don't work, and there are no "click" sounds or feel when I click. Fan never stops going, all processes are extremely slow (remember, this is a 16GB RAM computer and I am not doing anything other than browsing the internet at this point). I take it to Apple service, they tell me that despite only having 5 cycles, the battery is "bloated", which means it was either bad quality to begin with or stored poorly/for a very long time. They tell me it might be pushing the trackpad up and might be causing the overheating and other problems, but they can't service it because it was handled "unofficially" (whatever that means).UPDATE: I had to replace the entire topcase for $750 dollars, and found out that this computer is a 2.5GHz, not the 2.8 described in the product title. JemJem has shown no willingness to help even with the cost of repairing this horrible, misadvertised product, so I cannot more strongly recommend that no one buys a product from them. For the $1840 I already put into this computer I could have bought a newer one directly from Apple.
