sorry for today, but I was angry.
I wanted to try block level, I did not want to pass to an obtuse old, attached with their own ideas.
Now, after they are five years that I use rls. I have tried other brands before, but no one like rls. it is useless to say on forums that are the same, that you can do believe a beginner, but not to me.
if (bls) or other brands, when you squeeze the wedge. they bend, the line of 2 mm tiles, becomes 4mm. you have to take the rubber mallet and tighten the tiles. all lost time. the speech, the price is another thing. if you want to spend less, do not expect the level of rls.
after the blue blade, another closed discourse, for me. (Puff, finally I tried, THE BLOCK SYSTEM)
