I had previously purchased a more expensive and heavier duty cover for my series X. It was a bit on the heavy side as was waterproof. Probably meant more for kids or people who have kids. It also had a strap at the bottom of the gap where the cables go through the cover and this obstructed the cables. A failure in the design. You could just cut this off but I believe that you shouldn't have to tamper with any new product in order to get it to work as intended so I sent this cover back. The Mcbazel cover is faultless. Cheap, light and slips on with minimal effort. It's probably the best dust cover that I've ever used.
