Rob's hub, all the yak in description. Delivery trekov, building.
Ordered April 21 arrived June 24 to Toronto. Longer wait than expected but perhaps Covid delayed. Product as described. I am overall happy with order.
It's fine.
Delivered to Switzerland in 88(!) days. I know about the COVID-19 and all related problems, but this is my personal record shipping time regardless. Otherwise this is a great item, works as designed. USB 3.0 speeds are present. Power is also present.
Everything is fine, until I checked
Looks decent, I will check what power supports, if up to 3A, I will add an additional feedback :-)
It came in 26 days by the postal company sdek, apparently cute, but the quality is immediately visible plastic trinket, curve, cord very short didn't have enough length, the power plug and the USB plug did not stick at the same time because the insulation rests together (had to be cut with a knife) work simultaneously 7 flash drives quietly and without BP, But here is 1 terabite hard drive is not read and does not see at all, let's see how it will not break down quickly?
Class A USB hub. Kupuyu at the same time other and arouge. The skin of this House has a history of vimikach. 3 One USB retail can be zrobity 4. After passing the peroxide, the flash drive on the Insha, if the stony included in the hub-all pratsiu. On the washable laptop one hour can the windows of one USB port of Healing 4 flash drives, Totto 500 Ma is additional. It is not necessary to live alive, then it is the dodatkoviy retail for the living room. In the reception I buy the podvnistu zadoveniy. They delivered to Ukraine for the city. Recommend.
The hub is indeed USB 3, everything works as expected. The power switches cut the power only, which is sufficient.
Everything came safe, but the first 3 USB inputs work, and the other 4 USB inputs do not work, I will open a dispute. I did not communicate with the producer, then I will supplement the review.
