Product Reviews

  1. It’s a plug

    Posted by Plug Master on Mar 12th 2019

    It is larger than some, smaller than others. Fear it.

  2. Fits like a plug

    Posted by James on Oct 1st 2018

    "Fits like a plug" holds water and/or purple power to get to those hard to reach places in the neck of the bong.

  3. Works Perfectly, Good Service

    Posted by Unknown on Dec 2nd 2015

    It works exactly as described and my order was processed and shipped quickly.

  4. Newest version is indeed better!

    Posted by MBobber on Sep 22nd 2015

    The original version had too steep an angle/taper so when used with water/slippery cleaning solution, it didn't always stay in.
    This new version with a shallower taper works great!
    Great help for keeping glass pieces clean.
    Hot water + prowdered brewery wash + Ratchett tapered plug to keep water in = clean glass
