100 Set Tile Spacers Leveling System Reusable Floor Leveling Compounds with Replaceable Steel T-pin for Wall Floor Installation, Fits 8-12mm Tiles

These do exactly as they describe with one, but a major, caveat. I'm pleased with their leveling, and the metal T is wide enough for some common smaller spacing if you are very careful to make sure it's perfectly centered. This is not the easiest thing to accomplish.The description says it accommodates 2-6mm gaps, but that is misleading to downright false. Using calipers, the center post of the T measured about 1.3mm rounded up, so you could gap as little as 1.3mm with the tiles slammed right up against it. The T measured 9.8mm across, also rounded up. What that actually means is the maximum gap is LESS than approximately 5.6mm ((9.8/2) + (1.3/2)). These are all generous rounding upwards, and also assumes the T sits AT the edge of the tile, without any of it underneath. Even .1mm under the tile isn't enough though, and I'd say you'd still be no better at .5mm. Think about how small that is, and how tiles aren't a perfectly square edge! So really, you can gap from 1.3mm to maybe around 4. That's to say, about 1/16" to 3/16".I docked 2 stars for bogus claims in the description about the gaps it supports, not the small range and small sizes, since that was somewhat clear by their claim of 2-6mm. It is mathematically impossible to get a 6mm gap with these, and in true practice you'd have to work very hard to get slightly above 4mm. At this price point there are far better tools for that.The packaging was also FULL of microscopic black plastic pellets that spilled out all over the place. Truly microscopic. They look like flea eggs. I think they're burrs from the holes punches in the black plastic for the metal cross bars, and they made an absolute mess that I'll never know that I actually cleaned up because of how small and everywhere in the carpet they went. I can't imagine how we're getting micro plastics in our bodies!

Had no issue using these tile levers on a smaller project, wasn't as easy to use as the spin kind, but worked!
