✅ – For stickers: clean your keys, peel and stick. For pre-printed: plug-and-play via USB.

❌ – Stickers add a slight texture change; some users dislike the bump. Pre-printed keyboards often use cheap membrane switches (mushy, less durable).

✅ – Works with built-in Windows/Linux/macOS Tamil input methods. Just switch keyboard layout in OS settings.
