USB Type-C Connector Securing Device

Mac / PC / USB-C / Thunderbolt 3 and 4 Devices
Secure your workflow by stabilizing any USB-C connection including Thunderbolt™.
Dropping a cable during file transfers or a work session can be devastating. ClingOn is designed to hedge that risk by reducing if not completely eliminating the slight and ongoing cable strain of external devices with any USB-C connection including Thunderbolt 3 and 4 ports.
The revolutionary ClingOn is easy to install. The soft foam interior forms a snug fit to the connector that helps eliminate the wiggling and pulling that leads to slipped connections on your external drives and gear. ClingOns rigid outer shell is made of hard plastic to protect your cable and features a strong adhesive to secure your connector to your drives enclosure. Its compatible with any USB-C or Thunderbolt device that has room for attachment.
Before you get to work, secure your workflow with ClingOn, the cable stabilizer.
NOTE: ClingOn is specifically designed to stabilize device connections. Using ClingOn on a Mac or PC or multiple ClingOns on a device is highly dependent on port spacing

Rating: 2/5 Great Idea...Bad Implementation April 23, 2020 I absolutely love this idea because I always felt that the USB-C/Thunderbolt 3 ports just didn't feel as secure as my thunderbolt2 ports did. So I start off by saying hats off to OWC for the idea and for making and offering it....I have a good deal of OWC products and am very happy with them so I expected another great product but the truth is though the idea is great the implementation is terrible. Simply put, these cling on Connectors are two thick to fit next to each other on most devices. Case in point my Mac mini has 4 ports but they are too close together that installing even one of these blocks the port next to it. This is also an issue on other devices that have multiple ports side by side. These work great on my OWC dock but it is clear that the dock was designed differently as the ports are further apart than 90% of my other thunderbolt devices. I believe if OWC could shave these down in size a tad to fit next to each other on a device like a Mac mini that it would be worth 5 stars!

Rating: 2/5 Too big to fit on both ports of my iMac 18,1 October 24, 2019 I have tried to use these to stabilize the connections between my two OWC Helios FX eGPUs and my 2017 iMac (iMac 18,1). Unfortunately, the spacing of my Thunderbolt 3 ports and my USB 2.0 on the rear of my iMac prevents me from installing these on both Thunderbolt 3 ports - the devices are simply too large, even if I trim the protrusion. Does work for one of my ports, so it solves half of my problem.

Rating: 4/5 Work great, but...... October 13, 2019 I had persistent problems with USB-C connections between my Mac Mini and the Thunderbolt 3 expansion dock as well as to some external drives. These little stabilizers solved much of the problem, in places where they would fit. They did fine on the dock, but the back of the Mac Mini has the C ports a little too close for these to fit. They need to be thinner on the sides, probably just a few mm would suffice. Or even better, create a single piece that could be attached to back of the Mini that would allow access and stabilization to the four C ports on the latest Mini. The connections on the external drives seem to be stable, but the Thunderbolt Dock and the Mac Mini are problematic.

I don't know what the exact issue is with these USB-C connections, but they all seem to lose connection with only slight movement. It's happened with the Apple cables, as well as the OWC cables, so perhaps it's an issue with the actual size of the metal insert. But these stabilizers have definitely helped.

I would recommend this item to a friend! This review is from OWC ClingOn USB Type-C Connector Securing Device (5 Pack).
