    I like gravity bongs.

    My experience with this item has been great. I had purchased this item before from another store and had insurance on it. I dropped my phone on it, and instead of my phone cracking the base cracked. Instead of dealing with the insurance I bought it from 420 Science because they are awesome and have great customer service! They are the best!

    Using the item, using customer service, ....all amazing ! Can't say enough about my gravitron, and when I broke some glass parts along the way, CUSTOMER SERVICE PRACTICALLY JUMPED THROUGH HOOPS TO GET ME UP AND SMOKING AGAIN ! Can't thank them enough for a stellar smoking experience and great CS !!!! Steve Molenkamp

    Not made of the best material.

    I’ve had this replacement base for maybe a few weeks now. When I got it in it was perfect. Now, the base has warped into more of an oval shape. It’s now a problem when I smoke. The water in the base shoots up the side walls of the base when inhaling, that ends up leaving me having to clean up the water that comes out.

    Hi Ashley, Thanks for taking the time to leave us a review on the GRAV Gravitron Replacement Bases. These bases are actually made with borosilicate glass and should definitely not be changing shapes. Would you be able to shoot over a few pictures or a possibly a video to 'help@420science.com' to give us a better idea of the exact issue that you are experiencing? We would really appreciate it and are looking forward to hearing back from you.
