Useful
Seeing as Apple decline to sell their new iPhones with a plug, this was a handy addition until I was able to get a couple of USB C blocks. I have now moved it to my car to adapt my USB port there and it works perfectly and doesn’t seem to slow down the charging (using a genuine Apple cable with it). Good value for money and fits perfectly. Very simple to use and look fine despite being silver where my cable is white - I’m not bothered about such aesthetics!Recommended to someone else who needed one for an Apple Watch and they also found them good quality.

Does the job.
Does what I need. I have a power bank that does not put out USB-C and an aniti-spy camera detector that needs a USB-C port. So now I have the option of plugging this into my power bank and then plugging my camera detector into it. Perfect.

Essential purchase if you have a new device with only USB C cable
I recently purchased a Samsung Galaxy watch that just came with the charging base that has a USC C plug on the end. All my power adapters have USB B sockets so I needed a cheap and practical solution to avoid having to buy a dedicated USB C power adapter.After a bit of searching around I settled for the PORTENTUM USB C to USB B Adaptor as it was one of the most compact versions I could find as I didn't want anything bulky.It is well built and works perfectly and is compatible with both plug in power adapters and powered ports on laptops and docks.I would happily recommend it over buying a new power adapter.
