Excellent...very pliable, flat profile makes for easy routing.
I purchased this to replace the original that came with the camera. I have now destroyed two of them with cord wrap/wild slew events that pulled the connector apart. I have cheaper USB 2.0 cables that are molded at the ends and work just fine with my ASI385 camera. I like the flat cable but it’s simply overpriced, not as durable as it could be and not necessary for my needs. I now use an extension cable and loop the ends to provide some strain relief.
ZWO now ships this flat and super-flexible USB3.0 cable as standard equipment on their Astronomy Cameras, but if you're like me and your camera came with the stiff gray cable then this is a wonderful upgrade! This cable is much easier to manage as your telescope slews from one object to the next and is also more compact for storage. I'd like to thank OPT for adding this item to their inventory at my request.
