I ordered this 5x5 a while ago because I was missing a 5x5 in my collection, so I ordered this one specifically because it captured my attention. Out of the box, this puzzle is a bit dry (at least for me it was), so I recommend setting it up or at least applying lube to it so that it becomes smoother and have a more enjoyable feeling. It doesn't have any adjustment system (well, it has a **** and spring mechanism
but who counts that), but I personally think the factory adjustments are perfect. As for the magnets, they are moderate-strong, and there is a ball-core but I don't really feel it that well (then again, maybe because this is my first 5x5). It doesn't have an excessive amount of accessories, only a screwdriver, a cleaning cloth, a pamphlet, and a cube collector card (I think that's what it is). Overall, this 5x5 is definitely a go-to option whether as your first 5x5, or as an upgrade, as long as you don't mind the price (which is worth it only if you know you will use this cube a lot).
