Bests & Worsts Reviews from Amazon

Despite what the description says, these connectors DO NOT MAINTAIN USB 3.0. To many, this may not be important. I own a small business (networking and digital media) and have many many applications that require USB 3.0 or better. I bought these adaptors for several applications and as backups to carry in case I did not have a USB C or had a bad cable on a job or at home. We tested these adaptors here with USB 3.0 cables of 3 different brands and found that data speeds through the cable dropped to 1 GB/s (sometimes less) from 4 GB/s without the adaptors. The description clearly says it maintains 1 GB/s but is good for up to 3 and works with USB 3.0. This is false. Once you put this adaptor on a REAL USB 3.0 you have downgraded it to a 2.0. We have several devices that ONLY work with USB 3.0. Device 1 - Media conversion device for digital menu boards - Requires both the power and at least a constant 2 GB/s of data speed from a USB 3.0 cable. This device will not even work or show up on a 2.0 cable. We used a USB 3.0 cable that was Type A on one end and Type C on the other end and of course it worked fine. We then took the same length and brand of 3.0 cable that had Type A on both ends and put the adaptor (this product I am reviewing) on and the device would NOT work. The cable was fine as it charged a phone so this meant the adaptor was working but was not properly designed for a real 3.0 application. Although it provided power to the media device (minimal I might add for some reason) it would not provide anything else to allow the device to operate. we then used a REAL 3.0 extension on the same cable without the adaptor and the device worked. Device 2 - Oculus Quest (Linked) - Doing a similar test as above. For those with a Quest, they know that the Link is VERY finicky on the cable... Using the adaptor, the Quest wouldn't even attempt to link up or even allow Windows to recognize it as a device. The charging DID work through the adaptor but VERY poorly. We tried both adaptors that came in package with same results. We also tried all 6 USB 3.0+ ports on the first PC and same with the other. we also tried the virtual ports on the RTX 2080ti cards in both PCs that were Type C and still no results. Bottom line is this, these adaptors shouldn't even be have any mention of USB 3.0 compatibility in their description. Take it from a 15 year professional in my trade... These adaptors are no better than ones you would find in an electronics department in any given store. OOPS, almost forgot about the other issue!! The length of the actual connector that goes into the device is too short for EVERY PHONE we tried to plug it into that had a protective case on it. In other words, we had to take the rubber or plastic cases OFF the phone to allow this connector to fit into the port to charge firmly. Otherwise, it would just fall out. The cases we have on our phones are not any crazy or fancy big cases...They are merely little scratch protectors that snap onto the phones. When I compared the connector length of these adaptors to the length of a Samsung charger cable.. these were slightly shorter and of course more bulky. The only thing good I have to say about this product is that they fit very nicely onto the Type A cable with no play or problems.
