StarTech.com Thunderbolt 3 to Thunderbolt 2 Adapter (Non-Reversible) - TB3 Laptop to TB2 (20Gbps) or TB1 (10Gbps) Devices / Displays - Black - Windows/Mac (TBT3TBTADAP)

Does the job perfectly. Plug and play. No issues

HDR does not work, though, despite them and cabling supporting it.

This adapter works perfectly. I use it to connect my Thunderbolt 3 laptop to my Caldigit TS2 docking station. The main problem it has is the "embedded" USB-C cable. It is very short and therefore fiorces you to keep the device next to the laptop. This is not always practical. For example, if you have a laptop stand on your desk, or even a laptop arm to place your laptop, the adapter will generally hang from the laptop in the air, applying tension to the wire.I have a laptop arm which is the worst as the laptop is quite high from the desk. I used double-sided tape to attach the device under the tray of the arm and run my TB2 cable from the device through the arm down to the docking station. Even so, doing a 180 turn with the cable to insert into the laptop is very tight and I think will eventually wear the cable out.I would prefer it if I could stick (with double-sided tape) the adapter on my docking station instead, but this is not possible due to the length of the attached cable.A much better design would've been if they simply had two female ports (TB3 and TB2) so you can run your own TB3 and TB2 cables, of whatever length you need. This would've been much more versatile and reduced the cost of the device.

This is an excellent device that works perfectly with Linux despite the "Windows Only" description. I use it to connect a work laptop running Ubuntu (20.04) to dual 4K 60Hz monitors and it worked straight away with no set-up or configuration needed.I bought this to solve an annoying problem I had with Startech's other very similar looking TB3 monitor adapter, the one with dual HDMI ports at 4K 60Hz. I was using that one before, but it suffered from washed-out colours on the monitors, which I discovered is a known (and still unresolved) problem with Intel integrated graphics and TB3 monitor adapters that use HDMI.As soon as I plugged this in instead I could tell the colours were fixed, and it's been running every day for the last few weeks without trouble. So if you're on Linux and want to connect a TB3 device to dual 4k 60Hz monitors, I'd highly recommend picking this up (it's far smaller and cheaper than an external GPU), even if that means buying displayport to HDMI adapters, as it'll work without any hassle and won't suffer from any colour issues. It also runs cooler than the HDMI equivalent and is even a bit smaller in size.

Like many people who have bought a new Apple laptop recently. The move to USB-C / Thunderbolt 3 has been extremely disruptive. I spent a fortune on new accessories. One thing I wasn't prepared to do was throw away my Belkin hubs and Apple Cinema monitors. I tried Apple's own Thunderbolt 2 - Thunderbolt 3 adapters; and they worked inconsistently. One day I would switch on my computer and the monitor or hub wouldn't work. For no reason. StarTech are a respected video brand, who used to make a well respected Thunderbolt 2 hub, so in desperation I decided to give their adaptors a chance.Let's get the negative aspects about them out of the way first. They are bulky, with the electronics coming in a case about the size of a stack of playing cards, rather than a small pack of chewing gum like Apple's own convertors. They're in a shade of dark grey only a sys.admin could love.But once you get over these cosmetic issues you get a product that just works. It is ironic that I had to go to a non-Apple supplier to get this most Apple of attributes. I can wholeheartedly recommend these convertors.

Bought this to connect a 2018 MacBook Pro (Thunderbolt 3) to a Drobo 5D (Thunderbolt 2) Hard Drive.Not only was the box way larger than any Thunderbolt 3 to Thunderbolt 2 adapters I've seen, but it failed to do the task it was bought for, didn't work at all.

I used this item to connect two Dell U2417H monitors to a Dell XPS 15 9550 laptop. To do this I bought two HDMI - HDMI 1 mtr cables from Wilko at £2 each, and made all three screens work independently by interfacing them with this StarTech.com Thunderbolt 3 to Dual HDMI Adapter - 4K 30Hz - (Windows Only Compatible). I'm running with Windows 10 and it was "plug and play". (My system is not 4K, but the adapter works anyway). All three screens appeared in "Display Manager", and were simple to configure. Only one problem on setting up, the system was silent, when I added the adapter it diverted the sound from the laptop speakers to the non existent speakers in the monitors, knowing that, it was a simple task to reverse the process and set the laptop speakers as the default. The Adapter works hard and gets warm, this is to be expected, it's not too hot to handle. The lead from the Adapter to the Thunderbolt port is 12 inches long; I would prefer longer, but it's not a problem. The Startech help desk was fast, knowledgeable and helpful. Update: Its now 26 June 2018, and I have experienced no problems with the above set up running 8-12 hours a day/365.

I've had this for a couple of months now, using it with a Dell XPS and two Asus 2k screens via Display Port. It just seems to work fine and solidly for hours on end with no glitches. I'm only using it for regular work so the 60hz on both screens is perfectly fine.
