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.

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 Dell WD22TB4 is a full-featured Thunderbolt 4 docking station that transforms your laptop into a complete desktop workstation with a single cable. With dual 4K display support, 180W power delivery, USB-C, HDMI, DisplayPort and Gigabit Ethernet, it covers every connectivity need in one compact unit.
The WD22TB4 is ideal for creative professionals, engineers and business users who switch between home and office. A single Thunderbolt 4 cable instantly connects your Dell laptop to dual 4K monitors, wired Ethernet and all USB peripherals — while charging to full speed at the same time.
With Thunderbolt 4's full 40 Gbps bandwidth, the dock handles simultaneous dual 4K video, high-speed storage and data peripherals without bottlenecks — a notable improvement over USB-C hubs or older TB3 docks that share bandwidth between video and data.

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.
The laptop was sold with a warning about worn keycaps. In fact they had been obviously vandalised (ex school laptops, perhaps?). The keyboard worked fine, and the rest of the laptop too. I'm using it as a file server, so I don't need the keyboard much. So very pleased, and also pleased with reboot-it's service - as always, excellent, and quick responses to any queries.
