Mine hits my speed cap of 15 mbps, but now importantly it's dependable. My wireless connection was prone to frequent enough lag spikes that games like dota 2 were consistently ruined by 10 freezes or disconnects. My house is fairly new so old wiring want an issue, though. Definitely an item for which you'd keep the receipt in case it doesn't work as well as it should, since the are many variables at play. For me, it's been an insane upgrade for 30 bucks.
