All in one and great for any science experiment that looks really professional.

This kit works pretty well for a small group. The electrode apparatus is too light. It is hard to keep it in place while placing the collecting tubes on it. It slides too easily thanks to its light weight. A moer dense base and taller collection tubes would be nice.

It works. I wish it was a little bigger and I wish the test tubes were not so wobbly. It gets the job done.
