pros:good for using pen drives only.
cons:bluetooth dongle does not work properly when attached to this hub,
wireless network usb adapter also does not work properly when attached to this hub.

I bought it from flipkart but i got a default device and i got it replaced...but its true that flipkart has the best service...the replaced product is working great and its worth spending money....but buy only for Rs 520...not more than that....as it worth's only Rs 520...

Works like a charm.Plastic quality is not that good...but it's okk . I wasn't able to charge my Tab by connecting it to a charger and the Tab to this hub..but for a cell phone it works well. Data transfer rate is also good

good product . and not very expensive. flip kart price is good. usb cable is enough . all ports are working. recommended for buyers.

I was worried at first when i ordered it as it is cheap,however now that i am using it I could not be more delighted.One can attach 4 devices simultaneously and all of them would work without a hitch,however i am not sure of its performance when use an external hdd but have plugged in my smartphone,nexus tablet ,two nano wireless receivers and everything works without a hitch.I must mention that it has a blue led light to indicate power on or off,the led is a it too bright, i mean irritating...

the Quantum USB Hub, is a great product and works perfectly fine. all hubs work simultaneously and can has a button too to switch it on and off...overall great product..

I bought it today. Plugged my Phone, Speakers, Cooler, Mouse
All are working just as smoothly.
Tried copying a movie on to my phone ( which happened pretty fast, dont know if its just my Ultra Sandisk ), played music on the speakers aloud simultaneously and still the mouse was working perfectly as was the cooler working.
Basically, though its deriving its power from a 2.0 and passing it four at a time, its working great.
( Might update my review later if I find any problem in future)

Still r...

When I ordered this, I was expecting some cheap quality product that would barely last a year. But instead I got a nicely built device. The cable is good and strong, and a foot in length, so no complaints there. There are 4 USB ports, each USB 2.0 supporting. There is also a switch on the device itself. There is a blue LED indicator, which is rather too bright and may not let you sleep at night if you keep it on. I had to put some colored cellotape on it.
The speeds are slower than USB 2.0, ...

Good product Worth Buying.
Buy it If you are in great need for it.
Pros: It has a on and of switch
It Has an indicator
4-ports

Cons:4ports are not enough for me(take it if your needs are just 3)
Plastic(but not Weak)
Not a great design(it doesn't matter me)

worth the money ,
decent for its price ,
could hav been little more stylish thou
