DjuiinoStarHigh-end Fidget Spinner, Unique Dual Bearings Design, Precisely CNC Machined (Stainless Steel), Premium EDC Toy DFS-01

I love it. Really heavy and spins a lot. I got it in perfect condition 🙌🏼🙌🏼🙌🏼

Spins freely and is well made. Third try it stayed spinning and didn’t stop till 4 minutes 29 seconds. Just wish it is a little bigger than what it is.

I bought the titanium version after my first official fidget spinner, the copper one. Was super excited getting the titanium as it's one of two materials I love when it comes to EDC. Titanium, also because you can anodize it if you're willing to play with some simple chemistry and electricity. That means this boring and dull silver can be turned into blue, gold, bronze, electric blue and blurple. Even upward to toxic green. Just google titanium anodization and you shall see!I open the box, and took the fidget for a spin but was somewhat underwhelmed. The fidget felt light and empty in hand. I mean, no surprise this is titanium afterall, light weight and strong. When spinning it also had some not so satisfying noise. Very subtle but it's there. It's a weird sound that bothers me. Copper version also has sounds but more unintrusive to my ears. I open the spinner and compared my two versions and the bearings appears to be different. Pretty sure the one in the titanium was inferior but I could be wrong. It was open caged and not sealed like the one in the copper version. Granted I could research for replacement bearings to upgrade it..BUT, as a fidget, this simply felt too light weight in my fingers. Some like that, but I learned I'm not one of them. Maybe I should've gotten the stainless but there's no point since I didn't need a boring silvery version but wanted to colorize it; anodize it.Sadly it would be too much for any fidget maker to offer various polish and color anodization since it's time consuming without driving up cost. I decided not to bother proceeding with any customization with the titanium version and will be returning it. It doesn't feel fun in hand compared to the copper version which I already have.If you want light weight and silver toned metal, but this. If not, Coper is far more luxurious. Now let me tell you about the copper version.I love copper, the weight, and it's ability to kill virus and bacteria on contact. If you're going to constantly fidget with your fingers might as well sanitize them at the same time so copper is the way to go. Unless you hate the smell of pennies.The one being sold, and at a really good price compared to some other websites, is a dark toned copper. I never liked it see the appeal of the dark copper. Rather have my copper patina naturally. If you are looking at the copper one I'm sure you already know about copper and how it patina over time. Likewise for brass but this doesn't come in brass; it should. I would also love to see a tungsten version, maybe not the price since it'll be super expensive.Got my copper version and first thing is do a spin, and the sound was satisfying and smooth! The weight, substantial in hand just becareful not to drop it. Copper is soft and you'll surely dent or scratch it. Sand the copper until you get the raw copper tone, and use finer grain paper to further polish it. When it eventually patinas and darkens more than you want it to simply use a salt/vinegar mixture paste to restore the raw copper shine again. Didn't take a picture of before and after but difference is still visible. See photos. The last photo the main body was reshined with salt and vinegar but not really different since I haven't gave it time to patina as it was only recently reshined.

I did not think that I am a fidget person. In hindsight though I do think people need to have something in their hand to help them cope with the struggles of life. The fact that you can hold a little kinetic energy in your hand is quite unique and to add to that it's almost a miracle that it can stay spinning. Mine spins for 4 minutes. It should spin 5 to 7 minutes, with the record held at longer times.The first one I had was defective, I returned it and got a replacement that works.The inter bearing and outer bearing work independently and one bearing can transfer energy to the other bearing, if stopped by human intervention. So yeah I'm hooked.Manufacturer's recommendation is that it NOT BE DROPPED as these bearings can be DAMAGED. I would agree. However you can easily buy replacement bearings from Amazon by referring to the bearing description that comes with the spinner. They even have a ceramic replacement bearing, that are claimed to be smoother with longer spend times. But they are at a considerable cost, some cost over $100.00, and people say there is no improvement in speed time.It is recommended that if you're not getting the performance you desire because of a sticking bearing, you are instructed to disassemble and reassemble, perhaps by swapping back and forth matching parts. That actually works. NEVER OVER TIGHTEN ANYTHING. Everything should just be just hand tight. That helps also. Special note, these bearings should never be lubricated, because attempting to do so will increase energy losses and decrease spin time. But if you feel the need to lubricate, it would have to be a very very very thin lubricant. Factory bearings come lubricated and are sealed, but if dirt gets in, rinse briefly in 99% alcohol dry and reassemble without applying lubricant.Best advice, contact the company if you don't get a spin time of at least 3 minutes. And I strongly advise care in disassembly or reassembly, mapping out the original layout of the parts. This is because, things don't always go together quite right if you swap matching parts, ONLY do so if you get a sticking bearing. I found it not easy. Best advice, don't mess with it, just ask for a return and replacement if dissatisfied.It is worth $100.00 and by far the best spinner out there. If you get a good one, you will know it because the bearings will interact equally with each other and make acceleration noises as energy is passed from one bearing to the next. It's a unique sound and it should sound smooth.

This is a dual bearing spinner, the outside ring and inner ring are independent of each other and can be spun separately. The machining and finish are excellent although I can force the slightest wobble. This is due to the play noticed between the R188 bearing and finger hold (caps) shaft that passes through it. Although for under $100 I cannot complain as this really does not affect the operation of the spinner. When table spinning just the outer ring I consistantly get approximately 3:45. When I spin both rings simultaneously I see that time increase to 4:30 on average. This increase is due to the inner ring fitting into the inside 6703 bearing, therefore when the outer ring spins on the 6703 the inner race wants to come along for the ride; spinning the inside ring simultaneously reduces the drag on the outer ring. The weight is exaclty 4.0 ounces or 113 grams. It's got a little heft but I like gyroscopic feedback I get when rotating it while spinning. I haven't quite figured out what the ball bearings are for that came with it.edit: My best table top spin with both rings is now 5:16
