No known downsides in my personal experience so far. If you need a light weight easy to put together rack to hold a couple of pairs of shoes, and not a pile of bricks or anything, then this rack is more than sufficient. This mouse did just fine and the conversion back to a regular mouse wasnt too difficult; its well built, has a nice texture, the braided cable is smooth and doesnt drag as much as some others, the clicks are. My granddaughter is crazy about Catboy and these made her very happy. They were surprised to discover they were crocs, and made of rubber. It?s warm and comfortable. These r my savior shoes. I only received these yesterday so cannot comment on their long term performance but, so far, I am really pleased with them. You wont regret it if you buy it. The Airpod Pro charging case just loosely sits inside this case.
