SanDisk Ultra Dual 128GB USB 3.0 Flash Drive

Very impressiveI honestly want to tell you all it has a great speed of 40 to 60 mbps on pc and 20 to 25 mbps on mobileI checked the speed in movies transfer from pc to Pendrive.In mp3 or photos it varies from 8mbps to 20mbps depending on the size of file.*It is the best ever sandisk pen drive, and amazon give me two day delivery without any charges.Works fine but heats up a bit.Works great on all otg supported smartphones And it's USB 3 and not USB 2, so the speed is a good.A lot better than purchasing cheap USB OTG adapter and plugging normal pen drives. But it's also good to have a OTG adapter in your arsenal since you might need to connect a normal pen drive some day.But the problem is it is very small and so, it heats up pretty soon.Although speed is great and look at the warranty 5 years warranty its good enough.You just have to submit your amazon receipt at warranty claim. If recipt is lost then you can use serial number written on the Pendrive.

The Brand SANDISK is most excellent pendrive for all their various capacities. I have purchased 16Gb, 32Gb & 128Gb. All of them are the best quality product worth the full value.

It is almost an year now. The device is working good. I had compatibility issues in the beginning because of its original formatting type. It was NTFS I think. After changing the formatting to FAT32 the compatibility part has been resolved. Being 3.0 version drive, it's reading and writing speed is fantastic.

Delivery was quick and on time as promised. Product is very helpful , it act's like a additional storage device apart from phone Micro SD card. A very useful thing to have , you can use it on your systems, laptop apart from your mobile phone

I always purchase everything I need from flipkart.. This's the first time, I purchased something from Amazon.. Delivery was outstanding! The delivery person's behavior was great!! This product is look'in just unbelievable awesome!! But it's getting extremely hot at the time of files transferring.. I'm not satisfied by this product.. I've been requested for return.. And the same delivery person has picked up the product today.. He was really awesome guy.. Don't know whether Amazon truly helped about it or not.. Let's see..

It's marvelous

No complaints other that haeting problem of OTG. If this they sort out nothing is there to regret about. One star reduced for heating issue nothing else.

Awesome gadget to have!! I loved this pendrive. Is very fast in transfering files in my phone. I bought it for use as storage drive for my phone to backup my edited videos and files that are yet to be edited (to edit footage from my DSLR) and I am extrmely happy and satisfied with this OTG+USB pendrive.
