I occasionally help folks with tech issues and I like to be prepared for whatever I’m going to run into. That means having all sorts of adapters and cables on hand. Occasionally you run into some devices with this older-style USB-B port, and I carry few of those cables with me just because I don’t have many and I don’t need them often. These adapters solve that issue. Rather than lugging around additional cables I don’t need much, I can simply carry these small adapters.In my tests, these work well, look good, and have an excellent build quality. I recommend them.

I'm using these USB-C to USB-C adapters to avoid needing a separate USB-B cable for my older devices. I use magnetic cables and put a USB-C tip in one of these so I have a quick adapter that connects magnetically to the cable. Quality is good, and USB-B connector has proper raised contacts inside. Data connection was reliable.

I know this seems obvious and it's advertised as a USB 2 which it is, but MAKE SURE that's what you need. It's an adapter. It works as intended. It's well marked. It's metal and well made. Not a lot more to say about an adapter, BUT to know what you need. USB 2, in it's day was considered fast, but NOT ANY MORE. Pretty much all knew devices are USB C. If you, like me, have an old USB cable running behind/under desks sticking this adapter on the end beats buying/running a new cable BUT only for things like printers/scanners or hubs for mice/keyboards where speed isn't important. That new USB C device you have is at least USB 3, which is TEN TIMES FASTER than USB 2 for things like DVD drives or external drives/devices. So you do not want to use this USB 2 to connect a speed dependent device/hub. IF you're trying to connect a hub, CHECK THE PORT. IF you have a blue USB 3 cable or port, this will not physically fit. For reasons I do not understand, the blue, USB 3 with an extra little hump to connect is still called type B and will not fit a USB 2 type B connection. You'd have thought they'd have renamed it, but here we are. Anyway, before you buy it, pull the plug you THINK you need to adapt to and make sure it's a squareish, white tip and not the double square, blue tip. If you're getting the right one, this adapter will work. It's a snug fit that won't come loose, and ordinarily would not be removed once inserted.

I've been connecting a laptop on a podium to an old Creative sound-card box via a very long USB A-B cable. Next month I'm upgrading to a newer sound-card box that has a USB-C jack instead of the very large and old-school USB-B jack on the Creative. This adapter will let me re-use the old low speed long cable w/o needing to buy an expensive special length high speed USB-C cable.- Best to ignore the "480 Mb/s" label - that number is just a theoretical maximum that is rarely approached. And this adapter isn't about speed, but for using with slow USB 2.0 devices that are now being supplied with USB-C jacks.- If necessary, I will update this review next month after I put the device in service. But I don't expect any issues.

I got this because I have a 3D printer (XYZ da Vinci Pro 1.0) that ONLY works over USB 2.0, so I can’t connect a standard USB type B printer cable into the printer and into one of my USB 3.0/3.1 ports. It HAS to go through a USB 2.0 port like on a dongle which I have but I hate having to do that.So this was nice to see that I might not only be able to bypass that requirement but also be able to use the newer standard of USB type C. It also worked over USB type C to USB type A into the laptop too.And I can confirm that it works! It connected to my laptop over its native USB type C port and didn’t require any additional software or manually adding drivers. I do believe Windows installed a new driver as Device Manager refreshed about 3 times after the “new device” chime.I should note that for some reason, the end of the cable going into the adapter was very hot to the touch. The adapter, itself, was not hot, though. This seems a bit concerning to me, but thankfully I’m never connected to the printer for long periods of time.I did some tests to see if this was the adapter or my cable:- The first cable that was hot was USB type C to USB type C. I tried this same cable on a standard paper printer and didn’t see any spikes in heat like initially. The room temperature was 73° F and the cable only got up to about 77°.- Tested on the same paper printer using another cable, a USB type C to USB type A and didn’t see any heat increases. It only got up to around 77° as well.- Tested the same USB type C to USB type A cable on the 3D printer and it got up to around 83° F and stayed there for many minutes with no new increases. The paper printer and 3D printer are in different rooms, so that may contribute to some of the difference seen here. Also just difference between devices and different outputs as well as physical locations of the placement of the port on the printer device. The sun shines on this area where the 3D printer is located while the paper printer is not near any windows which is another variable.- Tested again on the 3D printer using the same USB type C to USB type C cable and didn’t see any heat increases on the second try. The temp reached 83° F like the other cable.None of these tests resulted in the cable feeling hot again.I’m not exactly sure why this happened. My guess is that maybe my laptop was originally trying to pull electricity to charge the laptop prior to getting the right driver to recognize this was a printer and not a power brick and that’s why it didn’t happen again? The USB type C ports on this laptop can receive power, so this is a likely case, I am assuming. On the second time connecting, the driver didn’t need to be reinstalled and Device Manager didn’t refresh, so my guess is that this is the most likely reason here.It’s not unusual to encounter “jank” behavior like this when dealing with adapters like this. Everyone considering adapters like this should be aware of unusual behaviors like this to occur, though this one is one of the more serious behaviors you need to be concerned with.So my advice to anyone who gets this is to first connect your devices using the adapter, monitor the temperature and immediately remove if seeing heat spikes and try again and monitor once more. Perhaps you need to install the drivers and let the devices talk to each other for a moment and then try again.I will continue using this but I am going to remain cautious when using it. Being careful to not use it for long periods and not without being monitored. I advise anyone planning on buying this to do the same.

Works at USB 2.0 speeds for my printer. Makes it easier to standardize on USB-C cables.
