Cosmetic Grading Standards
For networking equipment like the SG300-28MP, cosmetic grading reflects only external appearance whilst performance remains identical across all grades. Excellent Grade units show minimal signs of previous use with only minor scuffing or abrasions, no deep scratches, cracks, paint chips, or broken/missing pieces. Good Grade units are fully tested and functional but may feature light scratches on external housing, more excessive case wear, small dings or dents, or small paint chips. Both grades deliver the same reliable network performance and undergo identical testing protocols.
Verified Reboot Refurb Quality Assurance
Every Cisco SG300-28MP undergoes Reboot IT's comprehensive Verified Reboot Refurb certification process, where all features and functions are meticulously tested using cutting-edge diagnostic software. Since 2001, Reboot IT has been an expert in the refurbished IT industry, establishing rigorous testing protocols that verify full functionality before resale. Each switch is subjected to visual inspection, connectivity testing across all 28 ports, PoE output verification, management interface validation, and burn-in testing to identify potential issues under sustained workloads. Any faulty components are replaced exclusively with original parts to guarantee reliable, long-lasting performance.

Good value and great quality
Fantastic service
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.
Great way to buy a computer
Always good, sometimes a little slow and steady, but always good :-))
I needed a quick cheap windows 11 capable notebook.
RebootIT had a bunch of 2nd hand stuff advertised.
This Dell 5310 was one of them, at the right price and spec.
It works brilliantly, although its not the prettiest notebook I've seen.
RebootIT were up front about the condition though, so I still got a better notebook than I expected.
Perfect thin monitor for my purposes.
Unit was in excellent condition as described. Dispatch was priority and prompt.
Just plain good old fashion service. Nothing more to say I guess
