I rarely write reviews but had to for the ONO Slider. I've had it for a few months and it's my absolute favorite. It's (almost) silent, definitely quieter than any other fidget I own, which is perfect for the office. There's a slight click depending on how you use it, but you can play with it a number of ways and it doesn't make a noise. I actually think about it when not at my desk because it's such a satisfying experience. I went with aluminum but will probably grab another in Ti. 10/10 would recommend.
