Lenovo ThinkPad X1 Extreme Gen 1
Wear and Tear
Owned for 3.5 years, used Daily
Stress Points- 1. Center screw on bottom cover. This must be removed to add memory or SSD's. The anchor for the center screw pulled out at some point. Fortunately, it hasn't shorted the motherboard and everything is still functioning correctly.
2. There is a defect with some Lenovo products that causes the laptop to fail to charge. The first time it happened, I had Lenovo fix it under warranty. The second time I discovered that I could just reset it by disconnecting the battery for a period of time. Later, I discovered that I could have just used the small reset hole in the middle of the bottom cover. 
Positive Remarks- This has been mostly reliable.
- Would you buy it again?
Yes
