My
FC-710 order from the seller Ebizcn just got here. Now this piece really falls under the "Cheap High Quality Bubblier" category which is the title of this thread. The piece itself is almost flawless with just a few almost imperceptible bubbles present... All for US$ 20! Cheaper than the exact same piece sold by Stevenlmz79 (Popular Glass) which is currently selling for US$ 36.96 with already includes a 25% discount.
It was smaller than I thought it would be. I haven't used it with herb yet as I still need to get a female to female adapter but I tested it with water and it worked just fine... The ball produced a consistent rattle which becomes more pronounced the more the air flow is restricted... such as in actual use with a vaporizer.
Can't wait to try this out and compare it with my current favorite for flavor and smoothness which is the 8" CCG Straight Fab. I will be updating this thread after I get to use it with my vapcaps.
