hi
I did used them, I just wanted to see if they any good, and I think they quite useful sometimes, when I am finishing tiling at the end of the day I installing them, next day I start tiling and clipping old tiles to new with plenty of adhesive underneath (little bit more wet too), they help to keep same level, when adhesive start drying tiles might drop a little bit, so I use these clips they seems work for this trick, a little bit shame that they are a little bit thicker then 2mm, they like like 2.05mm thick :incazzato:, I think for people who laying tiles them selfs they quite useful to keep the same level 🙂 but if you think next day you will try kick them like in video ant they will brake, then it will not gonna happen, they really hard to brake, to brake easy you need to have space like 4mm and completely no adhesive around they body, which is sometimes hard to do if you want solid bed, or you need keep cleaning around clip
that's my opinion
Thanks
