Tanga again offers the open-box Asus T-Mobile CellSpot Dual-Band 802.11ac Wireless Gigabit Router for $54.99 with free shipping. That's a tied with last month's mention and $25 below the best price we could find for a factory-sealed one today. It features wireless data rates up to 1.3Gb/s, dual-band support, and prioritizes WiFi calls.

Note: A 30-day warranty applies, but it's unclear who backs it.
