Pros: The full-size keyboard layout is good, with a full number pad. Although some keys are smaller (the keypad 0 is shortened to make room for the right arrow) they are mostly in the standard location. Sound output is very good (considering the lower bass from the speaker size), with no distortion at high volumes. The screen gets very bright and colors are good after software calibration. Up-down contrast shifting is minimal. Video card performance is amazing - I was able to eke out 50-70 FPS on Low and 30-50 FPS on Medium settings for World of Warcraft. MMOs and older games are very playable at native resolution (1366x768) with medium quality settings on the 5500 internal graphics. Although the included HDD is only 5200 RPM, performance was good overall at roughly 80MBps. The case is solid with no noticeable flex. All surfaces other than the screen bezel are "brushed metal" textured matte plastic and don't show grease or fingerprints easily. The laptop is very easy to upgrade. There is a single large bottom panel that exposes both memory slots, the HDD caddy, and the mini-PCIe slot (wifi card pre-installed and the antenna wires routed to the slot). Everything is reachable with minimal effort. All drivers are loaded onto the C drive of the laptop - no need to go to the Lenovo site to download them! I copied them to a USB thumbdrive as a backup.

Cons: The CPU won't recognize higher speed RAM - the hard limit is DDR3-1600, so if adding memory get the lowest CAS (at 1.35 volts or lower) rating you can. The CPU also won't recognize regular-voltage RAM. There are two slots for a maximum of 2x8GB. Key travel is extremely limited, around 2mm. There isn't much feedback from hitting keys. The NumLock key is right next to the backspace and will be hit on accident unless you get used to the layout. The battery is probably too small. In real-world testing I got about 3 hours of web browsing with the screen at high brightness. The laptop is low-power overall and could do a lot better with a bigger battery. The screen is TFT and has poor side to side viewing angles - although colors don't badly shift brightness is very affected. Up and down is not as bad as most screens of this type - just some color shifting depending on screen tilt. There are many, many hidden partitions on the drive for BIOS options, recovery options, and other things. Cloning the drive to a SSD was very difficult, and I ended up changing the BIOS boot settings to "Legacy" from UEFI-only and re-installed Win8.1

Overall Review: The BIOS and boot options are accessed by booting from a power button hidden next to the power port; there is no keyboard code for entering the BIOS. The wired LAN port has an attached flap - this is designed to stay in place as you connect the cable, it doesn't stay moved out of the way if you try and open it manually. The (small) power brick connector looks very much like a USB type-A port, there's probably the possibility of confusion if you don't pay attention to the port layout. 6GB of RAM seems enough for most uses, I ended up not needing to upgrade it to 8.

Pros: Good performance. Coping 2.5TB of data averaged 120MB/sec from a source Seagate 3TB drive. Seems to run cool even at 7200 RPM in a tight space with normal airflow.

Cons: One of the drives died after one day. I was careful to full-format both and copy data to them, after which I checked SMART for any errors, which there were none on either drive.

Overall Review: Interestingly, the failure of the 2nd drive was instant and total. I heard repeated click seeking sounds, and then Windows froze from lack of drive access. After reboot, the drive doesn't show up in the BIOS or Windows. I wasn't able to use my normal drive recovery tools as the drive could not be identified.

Pros: The included 32GB eMMC and 1GB RAM meant that no extra hardware is needed, install an OS and go.

Cons: eMMC cannot be recognized by Windows 7. eMMC cannot be recognized by any Linux distribution with the exception of Ubuntu 10.04.2. If you have a M.2 or SATA drive this shouldn't be an issue as long as you remember to install a UEFI-aware OS.

Overall Review: Hopefully other distributions will support the internal eMMC drive in the future - Apollo Lake is a very new platform.

Pros: Good speeds for both read and write, sturdy case construction. Encryption software pre-loaded for installation (EncryptStick Lite).

Cons: Slider to extend/retract the USB port is a bit stiff.

Overall Review: CrystalDiskMark 5.1.2 Stats: Sequential Read (Q= 32,T= 1) : 120.822 MB/s Sequential Write (Q= 32,T= 1) : 53.870 MB/s Random Read 4KiB (Q= 32,T= 1) : 6.443 MB/s [ 1573.0 IOPS] Random Write 4KiB (Q= 32,T= 1) : 0.812 MB/s [ 198.2 IOPS] Sequential Read (T= 1) : 123.752 MB/s Sequential Write (T= 1) : 48.646 MB/s Random Read 4KiB (Q= 1,T= 1) : 5.907 MB/s [ 1442.1 IOPS] Random Write 4KiB (Q= 1,T= 1) : 0.751 MB/s [ 183.3 IOPS] Test : 1024 MiB [F: 0.0% (0.0/29.8 GiB)] (x5) [Interval=5 sec] Date : 2017/04/11 9:13:21

Pros: Comes with SD adapter Read performance is bottlenecked by my Android phone, but appears to be over 20MB/sec

Cons: Packaging was somewhat difficult to open.

Overall Review: Formats to 117GB total size Write speed is between 9 and 14 MB/sec, I couldn't test this fully because it's encrypted and locked to my Android phone.

Pros: Arrived Promptly Works Perfectly at the correct timings Stickers aren't thick enough to affect installation

Cons: Packaging did not appear to be ESD protected, it was a simple plastic clamshell

Overall Review: I would definitely buy this RAM again for my other DDR3 laptops.

I had no reason to call the seller, and the correct item arrived on-time and in good condition.
