I'm very sorry, but I'm very disatisfied with the seller. Not because of he sent different item (instead of ordered TES1-03104 -15x15mm, I received TEC1-03104 - 20x20mm) - it happens, but he didn't admit an evidence, even I submitted pictures (see uploaded pictures) where you can see the seller sent different item. The size 15x15mm was very important for me, because of need to put it in prepared place. 20x20mm is too big for me. Also Aliexpress failed as judge - not consider the evidence properly. I must confess a little my mistake of my late reply in dispute time, but during hollydays I had to do other things, but the seller probably didn't want to deal about refund value, he only wrote that he sent the right item (see picture). I think it is not serious seller!
on point they work
