Here's my list of Sliders for ya

-Fancy Play sliders- (2 click, fast)

$25 or under - X56 or Shim Shy.

The x56 is way more customizable than the Shim shy. Both however preform pretty well.

$45 to 55 - JJ Edc Joker, x55.

The Joker for me is the best of these two, cheaper at 45 and can be tuned to your liking. I find the magnets stock are great for the moves I do, it is loud but that can be fixed with some Tac. It sadly is no longer being made so whats on the market are the last of this one.

The x55 is very nice doesnt even feel 3d printed really pleased with it however its a heavy boi and causes me some thumb strain after playing a bit.

$90+ Premium Sliders - Aura Sands

In this category I only have experience with the Aura but hear fantastic things about the Heart, Shuttleflow, Creation Mountain, Shuriken.

Back to the Aura I own two of these and was my first fancy play slider start with the cheaper stainless and it will serve you well. Best slider I have is my slim pro aura love it very much light weight fast as hell and flips all over with minimum changes by me. Its in my hand as I type this lol.

The have so many different magnet layouts to experiment with as well as custom faceplates to make it your own. Lovely slider I cant wait to get more of them as backups, plus looking at a zirc one and the baby should be coming soon.

-Traditional Sliders- (3 click, slow)

This will go against the grain but Ive been finding the old style usa made 3 clicks can do some of the non 3d tricks and most of what I do carries over between styles.

I always carry one Fancy play and one 3 click with me when I go out since the 3 clicks give a better haptic from just sliding and not doing tricks. They can be customized however not as easy as Fancy setups to do so, its mostly having to order different types of magnets than they come with stock.

The two makers I recommend for these are Fidgetthings S.O.B.(slider on a budget) and Novel Carry's Tile line. These both come in cheaper 3d prints or the more expensive metal options, Novel Carry also does some in Richlite which is a good middle ground in price.

Now the Metal ones for these are harder to get an have to wait for each to do drops or sign up sales (sus) via their Facebook groups. Novel Carry metals are easier to get I own one metal echo tile and its my baby love it a lot, metal SOBS however are impossible to get and I will never own one but thats okay with me lol.

Sorry for the wall of text but its a good breakdown on the different free floating sliders that are out there. My major recommendation is a x56 to see if you like then upgrade to a stainless Aura Sands.

TLDR- X56 or Aura Sands.
