Bought this product to replace my very old USB hub. Arrived with the furthest-right switch that won't stay down/clicked so 4th port unusable. I contacted support and with quick response, got a full refund while the product stays with me.
On initial use, the light would flicker and the connection to my devices would turn off and on but now they haven't done that in a while. Having a 4th port would've been great but this is still nice with the switches, the price and good customer service.
