Review on 🔧 Efficient Tile Leveling System: 400-Piece Spacers for Lippage-Free Tile and Stone Installation - Ideal for PRO and DIY Projects (1/8 Inch) by John Reese

Overall they do a great job of leveling and spreading tiles. A few hints. Make sure the thin kit on the underside does not protrude beyond the base of the spacer. You'll have to use a pickaxe or screwdriver to scrape off the excess or it won't break and removing the grout and base becomes a hassle. Once we got the hang of it, about 98% spread out. When you have completed the row, use the end of a wooden handle (I used a rubber mallet) and place it on the corners of the tile. Then gently tap the top with another hammer so all the tiles are packed well and tightly. It really nailed the distance.
