Muy buena calidad

I'm not diagnosed with anything but thought I'd look for something sleek and minimalistic to occupy myself with during downtime / during work. This is pretty much exactly what I was looking for out of a product.It's compact enough to go in your pockets, definitely silent as described and rolling it does feel like massaging your palms. The hand motion becomes second nature once you get used to it, it's satisfying in its own way. There's a nice weight on the aluminium version and the overall experience is like using an over-engineered toy in the best way possible.The only thing I feel the need to give a heads up about is the screws. At the time of posting there doesn't seem to be any FAQ response immediately available on the ONO website or much explanation of public forums.You get two 3mm hex keys included with the box. The screws are applied on what can be described as a threaded shaft for both rollers which turns independently from them, and [the screws] are thread locked (i.e. an adhesive coating has been applied to the screws to prevent them from loosening unintentionally). Practically this means the said shaft has it so turning one screw on one side makes the screw on the other side turn with it unless you have the other side secured, also preventing unintended loosening from using the roller.These are excellent measures against loosening which users of knock-off brands report about. Mine came in the box a tad loose on one side already. Let me say I've never fought screws *by hand* like I had to in order to tighten them here before, because the only way you can tighten or loosen them is to have both ends held down otherwise the screws won't turn independently of the shaft at all, and it's thread locked. The thread locking adhesive is definitely solid. I'd probably suggest using power tools instead of hands to tighten or loosen the screws because using the provided keys caused them to strip the screws when trying to do so by hand and it took all of my strength to remotely get them to budge - but once they do budge, they are significantly easier to turn from then onward. This is to be expected, since thread locking adhesives being tampered with usually requires a new coating to be applied.The moment force you apply (if looking at the screw from the top down) should cause the screw to rotate clockwise if you want to tighten, counter-clockwise to loosen. If you're still unsure, take your right hand and make a thumbs-up with your thumb pointed in the direction the screw face is facing; imagine an arrow pointing from your back knuckle (big ones) to front knuckle (the ones rings go over) for which way you should turn the screw to make it go where your thumb is pointing. The way I had to set the keys up to tighten was sticking the key on the top screw pointing to my right, sticking the second key on the opposite screw at the bottom pointing to my left, placing the bottom key against a solid surface and pulling the top key towards my body as hard as I could to tighten them. I would probably recommend to do it counter-clockwise to loosen first, as loosening the screws is a lot more likely to be easier to do in order to get rid of the thread lock coat first WITHOUT stripping the screw before it loosens, but I'm not sure how durable the screws are given mine have stripped quite a bit- I don't mind it, but other people definitely will.Long story short, the only way you're loosening those screws is if you have both ends held down with the keys and enough moment force is applied to turn them, so don't worry about the thread lock coating if you ever need to tighten or loosen the screws. Do the thumb trick and turn the screw accordingly, recommend you loosen first instead of tightening straight away. Yes, at first they may not budge at all, I train four times a week and I had to use nearly full strength to get them to turn at first. Probably would suggest getting a power tool to do the turning for you.Final note that even if you do decide to turn the screws and affect the thread lock adhesive, those screws aren't loosening from using the roller afterwards unless you have both ends held down with the hex key bits, don't worry about them, they aren't going anywhere.Pricey, but worth every penny. Don't get the knock-offs. Hope the information about the screws helped anyone who needs to tighten, loosen or disassemble the roller. Long read, but better safe and informed than sorry in my book.

Really good quality. I had the aluminum and theres a little weight to it which i like and super smooth no sound at all. And i got the junior size which was also perfect for me
