The Novitec Wifi Booster
Novitec Wifi Booster claims it's Wifi4, or 802.11 N, which maxs out at 600mbps. But, on their product description page, it says "Boost your WiFi signal’s speed up to 1200 Mbps". When you go to the order page it tells the truth, "Up to 300Mbps on 2.4G".
Novitec Wifi Booster website has lots of similarities with a bunch of problematic sites like BuyRangeXTD, HOCWatch, Cardieo, TurboTuuli, BuyBlaux, Blaux, BuyOshenWatch, GetTVBuddy, FeverPatrol, etc. These sites have lots of complaints from their users.
