Frequently asked questions

What does the warranty cover?

Our warranty covers all hardware faults, but please note it doesn’t cover accidental damage or software issues. However, we’re here to help with technical support for those matters!

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!

All-in-one Solution for Home Office

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!

Fair tech for price

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.
