[This review was collected as part of a promotion.] It took a while, but Dell finally has a good line of docks that support more than two monitors. Of the 50+ that I've purchased, only one had an issue out of the box, and warranty support was excellent. My only tiny complaint is that it could use more USB ports.
[This review was collected as part of a promotion.] This is one of the best Dell Docks with one exception. No Sound output. But with that, good luck getting a WD19TB dock. This one took over 6 months to come in.
