Intake & data wipe
Storage is wiped to a verifiable standard and the OS reset before anything is listed. Service tags and serials are recorded so the exact unit is traceable: the one in the photos is the one you get.
Real name · Real bench · Registered LLC
A real person, a real bench & a registered business.
Strommen Systems is a one-engineer operation in the Philadelphia area: I source surplus and refurb electronics, test them on the bench, and list them on eBay (seller slashinburn) with the full bench report this catalog carries. The point of this page is simple: to tell you exactly who you're buying from and how the gear is checked.
Bench test & report
Each unit is powered up and exercised: storage health, battery cycles and ports on laptops; power-on and basic function on lab and network gear; channels and noise on audio. The numbers go on the listing: quantitative, not "excellent."
Honest grading & photos
A condition grade plus real photos on request: neutral background, a serial-plate shot, and close-ups of any cosmetic flaws. No stock images, no flattering crops hiding damage.
- Grade A
- Fully working, minimal wear. Looks and performs close to new for its age.
- Grade B+
- Fully working refurb with normal cosmetic wear: light scuffs or marks, nothing that affects use. Flaws are photographed.
- Tested-Functional
- Verified to power on and perform its core function; sold as a working unit with the tested results listed, cosmetics as shown.
- For parts / as-is
- Sold for repair or salvage with the known fault stated. Priced accordingly; no working-condition guarantee.
Strommen Systems is operated by Mat Strommen and registered as Strommen Systems LLC in Pennsylvania. It's not an anonymous reseller handle. It's a named business with a fixed location in the Philadelphia area, a posted return and shipping policy, and one inbox that I actually read.
The inventory here is listed under the slashinburn eBay account, where you can see the feedback history and buy the exact unit pictured. This catalog mirrors those listings with the full bench report and specs an eBay listing has no room for; every item page links straight to its live listing.
