Review on CableDeconn Aluminum Multi-Function Thunderbolt Mini Displayport 1.2 to HDMI 4K & VGA Converter Adapter Cable for Apple MacBook Pro, Air, iMac, Surface Pro 2 3 4, Mini DP to HDTV Eyefinity VGA Adapter by Timothy Gonzalez

I used two of these to run dual monitors on a 2015 MacbookPro for almost a year. Please note: I use two, one for each built-in Thunderbolt port, each adapter only works with one monitor. I've recently used a standard HDMI connection elsewhere and found that it slows down the computer significantly, even for a single monitor, compared to using that single monitor or dual to dual monitor adapter. I was surprised that the system ran faster with two of those two monitors than with one monitor connected directly to the onboard HDMI port. Highly recommend as it runs smooth and seems to get the computer running faster than using the built in HDMI port.
