Pros & Cons

Pros

  • ✓ Listed compatible with ThinkPad X1 Carbon, Dell Latitude 13, ASUS Transformer Book

Cons

  • ✗ Capped at 100 Mbps, so it bottlenecks any connection faster than fast Ethernet
  • ✗ USB 2.0 interface limits throughput versus USB 3.0 gigabit adapters
  • ✗ No USB-C plug, so newer port-limited laptops need a separate adapter
  • ✗ Smays is a low-profile brand; check the listing for current warranty terms
