The only thing that I believe they could add is something for more support for the cold trap

Excellent value and quality.

The product is excelent with no doubts. Packing is perfect, is almost imposible to breake during transportation. It works perfect. Good quality. Higly recomended.

I had some issues with one of the pieces arriving damaged, however the seller was responsive and quick to solve the problem.This is a great set for what it costs, I am very happy with it.

Nice unit for the money! Very well packaged for shipping
