I have the T-Mount appointed aeroSling and have to say: 40 for a sandblasted Edeltsahlplatte with 3 holes and 2 rods? Outrageous! I have the article returned and even built, material costs: But 3 star still there, because the quality is ok and it theoretically makes it what it is: Hold! The screws and dowels (Fischer) are of good quality, but MMN completely oversized => rather tear the tape or the wall falls to fail as these Schraauben!
