Refurb for Less via ebay offers the refurbished Unlocked Asus ZenFone 3 Max 16GB 4G LTE GSM Android Smartphone in Gray for $74.99 with free shipping. That's $55 under the lowest price we could find for a new unit and the best non-rebate price we've seen. (For further comparison, we saw it for $5 less with a rebate in January.) The phone features a 4,100mAh battery, which lasts up to 30 days on standby and doubles as a power bank. Additional features include an MediaTek MT6737 1.25GHz quad-core processor, 5.2" 1280x720 (720p) IPS touchscreen LCD, 2GB RAM, 16GB storage, 13-megapixel rear camera, 5-megapixel front-facing camera, 1080p video recording, 802.11n wireless, Bluetooth 4.0, microSD card slot, fingerprint sensor, and Android 6.0 OS (Marshmallow).

Note: A 90-day warranty applies, but it's unclear who covers it.
