TL;DR in angry‑nerd form
- Woot forum mod summary: "TLDR: Buy at your own risk. This is a Chinese scammer trying to sell overpriced trash. The seller admit themselves that this is fake cat8."
- Another Wooter: "These aren't worth it… They're not even reaching Cat 5 speeds… This item is a scam and is not cat 8."
- Reddit: flat "Cat 8" basically can't physically be real Cat 8 because Cat 8 needs so much shielding you can't squish it into a lasagna noodle. "There should be no such thing as flat Cat 8… what you have is a fake."
Greatest hits from problem reviews
- "Incredibly rigid… pain to lay and when I had a bend in it I was getting packet loss." Translation: bends = your packets fall off the cable and die.
- Woot comments say real‑world speeds sometimes don't even hit Cat5, which is impressive, because failing to beat 1995 is a skill.
- r/HomeNetworking: tons of "bought Cat 8, got slower speeds than my old cable" and "thousands of idiots leave 5‑star reviews for cables that barely meet Cat3."
- General verdict from networking Reddit: Amazon/Woot "Cat 8" is "essentially a scam and often fails to even meet the standards of Cat6… avoid Cat8 altogether."
What the cable actually is (in reality‑land)
- Likely just a generic copper (or copper‑clad aluminum if you're unlucky) patch cord that sometimes works fine at 1 Gbit, maybe 2.5/5 Gbit on a short run, but absolutely not verified Cat 8 and definitely not magical 40Gbps over 50 ft.
- Networking nerd consensus: if you want something real, buy boring, round Cat6a from a reputable brand; "the scam… isn't to trick people who actually know they need a Cat8 cable, it's to scam people who don't know what they need but see a bigger number."
So, use it as a cheap patch cable if you already bought it, but if you were hoping for data‑center‑grade 40G performance out of a $5 flat braid, that dream belongs in the same folder as "free 8K HDMI cables that improve your FPS."

How long did you spend putting this together
Reddit's r/HomeNetworking folks recommend Cat6a for multi‑gig all the time: "Cat 6A will work… ignore CAT7, CAT8… Cat 6/A solid‑core cable… will support up to 10 Gb."[2] Another thread sums it up as: "Cat6 will handle 10Gb up to 180ft… Cat6a will handle 10Gb up to 325ft… There would be no advantage whatsoever for using a Cat7 cable."[3]
For mesh backhaul, even eero's own docs just say "stick with Cat6 or higher for the fastest speeds and least interference," no mention of Cat8 wizardry.[1] In other words, buy normal round Cat6a from a known brand (Cable Matters, Tripp Lite, StarTech, Monoprice), match the length you need, and you'll be set for your 2 Gbps link and even 10 Gbps later.
