After 1 year of use, I can say that the base is very stable, sturdy, and fits perfectly with the Singer press.

In order to fit the super nova, we had to make new holes ourselves. The press still moves from its position. The bottom part is stable, but the top part is not as much.

Huge is the space it occupies compared to a previous base that existed in the market.
The legs are like a trap to stumble upon as their size and opening cover a lot of space... It is stable, hence the two stars.
