Good quality!
Very nice key caps. Sturdy and pretty much all are the same size and form, so they look good. Some didn't work for my specific board, so I ended up using only the white ones and the Esc key. They have a very soft, kinda velvet touch, and are easy to install. Some individual caps seem to have some flash inside the + hole and could be a little hard to insert at first, but nothing that bad.
