Thanks Julian, it's not professional but I'm proud of it.I can't compare leveling system as this is my first time tilling but I'm happy with it. From the usual complaints...no chipping the tile and two clips broke...but I blame not pressing the plier firmly down when pushing the wedges in.If I had the chance to start over I'll go for any system with a flat base...so the base it's not in the way when trowelling near the edges. For professional this can sound silly but I'm always worry that the little jump will leave too much or too little adhesive behind.John Paul is right, they where laid first.Paul...... I bit of truth in there but mostly because I can't wait to see how it looks without them
