Vitrex LASH150 Plastic 200mm Tile levelling spacer, Pack of 150

Website says for floor tiles, box states for wall and floor tiles!!
I would not use on wall tiles they are useless as the spring in the plastic of levelling is so great it will stop the tiles from forming a good bond with the adhesive. I bought these in store (didn't look on website where it states for floor tiles only) and regretted it having tiled 18m2 and the tiles not bonding.

Once you get the hang of these little clips, they make tiling an even wall so easy! I can’t imagine tiling without them again! You will need a lot of them to do the job properly but they are well worth it!

I've just finished tiling my 15 sq metre kitchen floor using these.
I couldn't have made it so level, without these.
I'll use these again when I tile my middle room in two months time.

I have used different types of these before and they are brilliant but the piece you put under the tile in this one pushed the tile away from the wall so it doesn't rip. Waste of money and looks like I will have to re-tile the wall
