Spigen LD302 Large Desk Mat 35.4" x 15.7" - Non-Slip Rubber Base, Waterproof PU Leather Surface with Magnetic Cable Management - Perfect for Home Office, Gaming Setup & Workstation Organization (Black)

I really like that the mat is large. I've always liked to keep my desk mat right up to the front edge of the desk. I've always liked to have my keyboard pushed far back, almost to the back of the mat, but I don't want to feel the front edge of the desk under my arm, so I occasionally have to adjust the mat, but typically only once a day.The disappointment is the magnetically-held cable holders. First, the magnets aren't strong, and second, the holes aren't very big at all. I'm only trying to use them with charging cables, but even the thinnest charging cable is larger than these holes. I might try using a drill on them, and hopefully I don't ruin any.For the magnets, I already have some ultra-strong small circular magnets, although in my case, they're a little bigger than the removable cable holders, so they stuck out from the sides. The solution that works for me is to put those magnets on the bottom, below the cable holders, and the magnetism works to keep the holder in place. Without the additional magnets, they feel strong until you actually put a cable through them, and the tiniest movement of the cable releases the cable holder from the mat.Maybe they meant them to be removed when the cable is actually in use, but that's not necessarily how I want to use all of them. I can see that it's a good idea for some cables I'd want to use, and I can still remove them when I want with the additional magnet.I did later find a 6 pack of slightly smaller round magnets that I can use between the mat and the cable holders, instead of underneath, since the magnets underneath were making the mat not lay flat at the back.The separate discreet magnetic cable holder they sell that I'll be using in addition uses the same weak magnets, so my solution for those is the same. FYI, even the single holder that has a larger hole that comes with that isn't large enough for most of my charging cables.A third issue I have with the cable holders that came with the mat is that there are only three of them, although it seems that the mat has five magnets in place below them, so there are positions for two more. Since the mat only comes with three holders, that's why I also bought the discreet holder to supplement the mat's included three.Overall, I'm satisfied for the price, which is thankfully much cheaper than directly on the manufacturer's website.
