Wireless keyboards have come a long way in terms of reliability and performance, and most modern wireless keyboards offer stable and consistent connectivity. However, like any technology, there may be occasional issues with interference, signal drops, or battery life. It's important to choose a reputable brand and follow the manufacturer's instructions for proper setup and use to ensure optimal performance. In general, wireless keyboards are reliable for everyday use, but it's always a good idea to have a backup wired keyboard available in case of any unforeseen issues.
