This piece is great! When I purchased the hands free vaporizer model, I noticed they had hydrators available and knew I had to get one - I went with the mini because of affordability, small size, and reduced drag (less water to pull vapor through). The mini hydrator has a smaller chamber so you don't have to clear large amounts of vapor with each hit. I liked the small, compact size of the hydrator - it is easy to package, doesn't take up a lot of space, and sufficiently cools the vapor. Also, the glass feels solid and substantial, and the design is great. There is a truly noticeable difference between vaporizing with and without a hydrator. As you take a draw of vapor, the mini hydrator "purrs" while the vapor diffuses through the carefully cut slits in the downstem. This mini model percolates the vapor really well - it is so smooth! Cleaning it will also be convenient, due to it's small volume, because I get to use less solvent to dissolve any vapor condensation that forms inside the chamber. I get a clean, smooth, cooled hit of vapor each and every time, guaranteed. I would recommend this mini hydrator model to anyone and everyone interested in Vaporbrothers and vaporization in general.
