Newegg offers the refurbished Logitech K400 Wireless Touch Keyboard, model no. 920-003070, for $24.99. Coupon code "EMCAKNS25" cuts that to $16.99. With free shipping, that's a buck under our mention from summer and the lowest total price we could find. (It's also $8 under the lowest total price we could find for a new unit.) Features include a 33-foot wireless range, built-in 3.5" touchpad, and media hot keys. Deal ends January 31.
A 90-day warranty applies, although its unclear who backs it.
