I was sent a "
McFinn's Glass Carbon Filter" (made for combustion water pipes) recently to try with the LSV.
The man that sent it to me swore that it gave much better hits that the LSV transfer wands, so I agreed to try it. (Incidentaly the man sells this item, but for a higher price than it can be had for directly through the maker Scientific Inhalations).. in fact he sells it higher than does the reseller "AquaLab Technologies".
This piece was made to house cotton and carbon filters, which I refused to use. The gentleman explained that used alone without the filter material it was still the best LSV wand that could be had.
The LSV wand would be VERY hard to improve.
I did give it a fair chance, but it was by NO means better than the LSV wand!
There is a place to stick a screen, although it does not fit snuggly. This screen sits farther back from the heat source than the screen in an LSV wand, so it took a bit more pull heating the "load".
The angled mouthpiece was comfortable.
The hits, however were not better, they were about the same and there was more glass surface to attract oils than on the preferred shorty transfer wand. This made for more work later when it was cleanup time.
There was also the portion of this filter (that the man called a wand) that prevents carbon from getting through. I found that this impedance also collected oils that I could have been consuming!
The person that sent this to me, said that it was a great mouthpiece OR wand for the Da Buddha.
We tried this, but found that it was way too "jury rigged" for comfortable use.
