UBreakIFix did a wonderful job of fixing my 2013 Macbook after almost 3 months of it acting finicky due to liquid damage. My Macbook got liquid damage back in April, and I initially sent it away to a place in California to be fixed. After getting it back, It worked for a short period of time and then it died again.
I then brought it to the Mt. Lebanon PA store, and they told me the repair shop in California did a poor job--the shop had replaced the battery but didn't do anything to the damage that had been done to the logic board. UBreakIFix helped me get a partial refund from the repair shop in California and replaced my logic board. That replacement let me use the computer, but it was so slow that I brought it back. I got a replacement hard drive, it started working fine, and I thought I was done with repairs.
But a short two weeks later, and my computer wouldn't turn on. UBreakIFix kindly put in another new logic board and absorbed the cost under warranty. After a few frustrating months of taking my computer back and forth, it's finally up and running 100%, and the employees were extremely helpful and kind about all of the replacements. The free diagnostics are super nice, and I trust them to not overcharge like the Apple Store might. I'd recommend the store to anyone in need of a repair.
