Apex series gaming keyboards from SteelSeries are both available with a full-size keyboard layout and a more compact TKL version. The full-size gaming keyboards all come with a numpad and anti-ghosting which prevents keyboard failure when multiple keys are pressed at once.
The full-sized Apex gaming keyboards come with either adjustable mechanical switches or whisper-quiet gaming switches that last for at least 20 million keypresses and IP32 water resistance for preventing damage to the keyboard from spills.
All full-sized gaming keyboards from SteelSeries also come with RGB background illumination (either per-key or 10 zone illumination) and with dedicated keys for multimedia control.
Should you choose a full-size gaming keyboard, or should you go for the more compact TKL form factor?
The choice really comes down to preferences, and whether you need the alphanumeric numpad found to the right on a traditional full-sized gaming keyboard.
The TKL (tenkeyless) gaming keyboard is a more compact form factor of the gaming keyboard and excludes the alphanumeric numpad. The full-size versions of the SteelSeries gaming keyboards all come with a numpad, but also takes up slightly more space on the desk.
