QZ [1.3 Feet Long Cable, 5Gbps, USB 3.1 Gen 1] USB Hub for Next Gen Office Work Station, 4 Ports, USB 3.1 Gen 1 for PC and Laptops

There are 4 USBs and all are of 3.0+ interface (3.1 mentioned in the description but I can't say ). Although it fulfils all its functions like high-speed transferring (also depends on other devices attached), I found the cable quality a little bit poor. It is long enough but could have been a braided cable for long life. Nevertheless, it is a decent product and plastic is not cheap as I have been using it for 8 months now.

works great

Product looks good and sleek design, Its very space saving. The only negative aspect what i observed after using it 4 to 5 days is that, it does not immediately connect your device to the system. Example, I bought this product to connect my mouse and Keyboard as my laptop has only two USB ports which i can use it to connect other USB devices. When u switch on the laptop and hover the mouse, the mouse pointer will take a moment to appear on the screen, sometimes similar thing happened with my keyboard also, the lag is about 3 to 5 seconds, not more than that. I think it’s not a bigger problem as once its connected to the system, it won’t trouble me anymore. So overall, Good product. I felt the pricing was bit high. But, if you are okay with the price, go ahead and buy this. I did some research before buying this and I feel you can go ahead and buy this without any hesitation. More over in these times, we should support Indian made Products rather than buying any Chinese or for that matter anything made outside India. As per my research Quantum zero is an Indian company but this product is made in china, Shocking!!!.

Works as mentioned. Using it for more than 3 months and works well. The USB mouse works fine with this but the wireless mouse lags. The Ports are closer to each other, so if you have some fancy USB male ports all of them may not adjust together.

Worked well initially, but with extended use, developed an occasional lag response that can come without warning, but doesn't obstruct or hold up work. It's just the only small irritant in an otherwise good buy. Am continuing to use it and have no trouble running my universal receiver USB and designing tablet through it simultaneously. Have not used all ports together, just two at a time.
