Having previously purchased a Macbook specific dock, my colleagues with Windows laptops have been struggling with monitor dropouts and low refresh rates on the poor duality docks they were using previously. I have now kitted them all out with these and everyone is very happy with the dual 4k/60Hz and additional ports provided by these.
I cannot see anything close to the quality and value of these on the shelf for any less than double the price, if even stocked.
Thanks.
