Excellent product. The both memory cards (CAMERA memory card & MOBILE memory card) doesn't work at the same time though. But all 3 USB ports work at the same time, which is great actually specially for the OTG smartphones where you can connect your keyboard and mouse simultaneously at the same phone using a otg cable. I tried different types of cards and hard drives too & all devices are supported. But the downside is cable length, which is .5 Metre (not a deal breaker anyways) & the material of the product is not very sturdy could get damaged if dropped from 5 feet or so but I remembered the price I paid for the product & so I am getting much of it. There is also a warranty for the product but don't know from where I should claim.Verdict- A true Value For Money product. I recommend to all of those people who don't want to afford a pricey one.
