The radiator itself makes a high impression, for the price unbeatable. Why did I only awarded 3 stars, is simply because the sellers or whoever this is not specified at Amazon the correct dimensions. Website 66x66mm on the packaging were not correct dimensions, 64x64mm even by not sounds like much of a difference but if you already have a hole of 63mm .... But as I had not found any other square for MR11 lamps I was forced to build a washer. The seller has the recessed spotlights delivered very quickly!
