I have sevral of these adaptors and the reason is I have so many laptopr, iPads, Macbooks etc and they come in handy as hell. The build quality is alweays good and Omar products are stunning looking with the silver matt finish.
This is excellent adaptor and the only issue is the lack of SD Card slots which would be great if it had one. I understand that this is why it is cheaper. But I can totally recommend this product if you are just looking for extra USB ports.
If this is all you need then it is an excellent purchase and well worth the money being asked. Like I say the more ports they have the better they are for me as I have so many cameras and accessories aways with me. They fit into my laptop bags perfect and take up no space at all, also the cable is strong for now that is. We can elaberate on that more after I have used them for a while.
