Zek USB OTG Adapter, SD Card Reader, USB Adapter Hub, for Samsung Galaxy Tab 4 8.0, 10.1, Tab S 10.5, 8.4, Galaxy Note 5, Galaxy Note 6, Galaxy S6, Galaxy S7

This is one of the most unreliable products I ever bought. I purchased it so that I could review my travel photos on my Samsung tablet and while on a 15 day cruise I plugged the unit into my tablet and inserted my SD card from my camera. The unit promptly caused my SD card to require reformatting so it appeared that I would lose all of my photos. I then reinserted my card into my Nikon camera and the camera couldn't read my card and I definitely needed to reformat. I then shot a few photos with a spare SD card and inserted into the unit. I could see my experimental photos. When I tried it again by reinserting that same second SD card and this time it indicated that it couldn't be read. When I plugged that SD card in my camera it couldn't be read. The long shot of this is that it failed totally to perform and caused me to lose all of my vacation photos. Simply put this unit isn't even worth sending back. By the way this is my first negative review ever.

Works great with my Tab S. Small and conveinent. Thanks.

The OTG plug works fine for sd cards, micros sd cards and flash drives. Mine, however, did not work at all with a hard drive when powered. However, when I contacted Zek about this, I received an email stating that it must be defective and that I would get a full refund. Great customer service.

It fits my galaxy tab 4 10.1 it shows power and when I put an SD card in it the tablet does not do anything and the power light goes out on the card reader. So less Im doing something wrong it's junk does not work.

Nice product. Recommended

It only worked for 3 weeks. It always seemed to have a poor connection and then completely stopped working. Do not waste your money on this product.

It's excellent

Must have been defective, did not work with my device
