Sonnet Technologies Desktop Thunderbolt 3 ECHO-EXP3FD-TB3 Expansion System with 3 PCIe Slots Black

This is a well-built, well-reviewed device. Its compatibility with PCIe cards like Avid HDX is said to be superb. Where there are compatibility issues on the other end, they aren't Sonnet's fault, but the device is not compatible with the only Thunderbolt interface card currently made for the PC, the ASUS ThunderboltEX 3. The ASUS card uses a standard Intel Thunderbolt chipset (can't believe it is not the same one they sell to Apple), but it is an unbearable kludge to get the card into your PC, recognized, and running. The driver then complains the the Sonnet Echo is not an approved device. Bandwidth is low, and on some boots the Sonnet is just ignored. So, too early for this to be recommended for the PC, and I had to send mine back.

This product is supposed to be a Thunderbolt-3 expander chassis. It doesn't work very well for the most banal of reasons: the ports are mechanically challenged. The card that provides the TB3 ports is installed into a chassis which COMPLETELY blocks the bottom size of the outer TB3 assembly. When plugging in, the port barely reaches deeply enough into the socket to make a connection. It does make a connection, but the slightest movement can jiggle the cable free. It is ridiculous that in today's world of CAD/CAM software, the designers couldn't flag a mechanical conflict that prevents the reliable operation of their product.

Belivable quality with no issue. Delivered with 0.5m & 1m thunderbolt 3 cables.

I have many Sonnet products and this is my second Echo Express III, I love it, Sonnet has an exceptional quality in its products, very robust well built and they use quality materials.
