Hello everyone, http://www.grasscity.com/us_en/circ-perc-glass-bubbler-with-worked-color-sections-jailhouse-rainbow.html?#.VBzopRbCfdc here is the bong I consider purchasing, but I don't know what to do if any piece breaks like for example the bowl and the downstem seems like fused, if the bowl broke what should I do then? does it render it useless. the downstem connects to a huge circ perc, and I don't know how I am supposed to clean it if I can not take it out in my hand. and also http://www.grasscity.com/int_en/black-leaf-3-arm-tree-percolator-ice-tube-one-hitter-diffuser-downstem-black.html#.VBz3kBbCfdc there is this at a cheaper price... in terms of cleaning and the replacement parts, which one would you prefer and why? Best Regards.
