What is a refurbished device?
A refurbished device is a pre-owned item that has been restored to meet high-quality standards. At Reboot IT, we adhere to strict quality guidelines, ensuring that our refurbished products are not the same as used or secondhand items. We meticulously clean, test, and assess each device, replacing worn parts with high-quality components.
Unlike used items, which lack guarantees and rely solely on the seller's word regarding condition, refurbished devices come with assurance of quality and reliability.
What payment options are available?
We offer a variety of payment options to make your shopping experience as convenient as possible! You can pay using all major credit cards, Apple Pay, Google Pay, Shop Pay, Afterpay, Zip Pay, and PayPal. If you prefer, we also accept bank deposits and even cash for in-store purchases!

The Cisco 7921G is a rugged 802.11a/b/g wireless VoIP handset with a colour display, designed for mobile staff on a Cisco Unified Communications Manager (CUCM) network. Backed by a 12-month Reboot IT warranty and free standard AU shipping.
The 7921G is a mobile handset for staff who cannot be tied to a desk — warehouse pickers, retail floor staff, nurses, and facilities teams. On a Cisco CUCM wireless network it behaves like a full desk extension, with directory access, call transfer, and the enterprise features users expect, but with the freedom to roam across the wireless coverage area.
The colour display makes it quick to identify callers and navigate menus on the move, and the ruggedised design stands up to the knocks of a busy shift. The rechargeable Li-ion battery is topped up in a desktop charger or multi-charger between shifts (the CP-DSKCH-7921G desktop charger is a common companion, sold separately).
This handset is best suited to sites already running a Cisco Unified Communications wireless deployment — it is not a standalone SIP phone or a cordless phone for home use.

I was looking for an in-expensive all-in-one solution for my home office to replace my existing desktop and monitor. I found this EliteOne 800 on reboot IT for under $200. I wasn't sure what to expect. It arrived within two days!!!! I upgraded the RAM, replaced the HDD and installed Windows 11. This is unbeatable value and was the cheapest price online. Coupled with a 3-month warranty, Reboot IT are by far the best online refurbished retailer I have used. Awesome!
Great service. Product in great condition and exactly what i want. I wanted this for a specific purpose but i dont need to spend $900 on a new one.
Excellent work
exactly as described and works well , just like the staff down there. 10/10
Very happy, thank you
Just having trouble greeting it linked to the internet otherwise it’s okay.
Fair tech for price, good specs for era, serves the purpose. The black keyboard is an interesting rubber like texture clearly by design to pad the screen and avoid the keyboard touching. Screen is great. Still looking for magic formula to enable computer use in the bright bright sunshine. Keyboard taps are loud for someone who likes silent touch. The perfect PC has to exist, like build a bear.
