Check which layout and OS a keyboard is built for (several models are Mac-specific or UK layout) before you order. Our full ProtoArc review covers shipping, returns and what to check before ordering.

At $39.99 it is on the affordable end of ProtoArc's range ($9.90 to $292.95 across 110 products), and similar items from other brands run $49.99 to $99.99.
