Redragon K670 Full-Size Review — Best Budget Mechanical with Numpad

The Redragon K670 answers a specific question: what’s the cheapest full-size mechanical keyboard with hot-swappable switches? At $47.99 with 104 keys including a numpad and hot-swap sockets, it answers that question well. If you need a numpad for data entry, accounting, or any workflow where number input matters, this is the budget pick that keeps it while giving you a genuine mechanical keyboard.

Most compact mechanical keyboards at budget prices drop the numpad first. The K670 keeps it. For users upgrading from a standard office keyboard who need every key available — numpad, function row, home cluster — the K670 is the direct replacement that adds mechanical switches without changing the layout they’re used to. The transition is minimal: same key positions, better switches.

Hot-swap sockets accept MX-compatible switches. The stock Outemu switches are entry-level but functional, and the sockets mean you can upgrade to Gateron, Akko, or any MX switch later without modifying the board. Per-key RGB covers standard preset modes. Build quality is plastic and solid for the price.

The full-size footprint is the main drawback. It takes up desk space that compact keyboards don’t. If you’re desk-space constrained, the K628 75% saves significantly on footprint for $5 less. But if the numpad matters and you don’t want to spend $80+, the K670 is the right buy.

Verdict

The Redragon K670 is the budget answer to “I need a full-size mechanical keyboard with hot-swap.” 104 keys, numpad included, at $47.99.
