Works as advertised easy to fill and looks like it will last a while. I like that I can fully open it and replace the beads if necessary should they every need replacing.
These gel jars work great! I never have to worry about my humidor or going through the awkward process of filling sponges... simply fill the jar with distilled water and set it in the humidor. I actually have 2 in mine b/c I have a large humidor. Works great!!!
