I have been doing tests, and have for 60 days now.... so my results and comments are not guesses.
Also since I do not use water often, I used a number of local Patients as test subjects.
I am about to reveal something that some here will find interesting/revealing... and also helpful to those that are on a budget.
t-dub made a believer out of me.
I experimented with cranberry juice, and saw what it did .. so I invested in 1/2 ounce of RezBlock for 19.95.
I am still irritated at the oils wasted and left behind on the glass, when using waxes.. but that was improved somewhat, and the smell also was more tolerable.
So thanks to t-dub, I played with water filtration some more.. and bought a second bottle of rezblock.
I had found the ingredients on their website, so I copy/pasted the actual ingredient list intact.. and a few brands of Health Food Oriented Cranberry Extracts popped up.
Most were expensive, but I found one that was $5 for a full ounce (free shipping if you buy $30 in merchandise) I got 6 one ounce bottles of this stuff. (
Cranberry Extract)
I tested it and it smelled and behaved the same. I gave 10ml of each to a local compounding pharmacist that makes organic extracts on the side..... he said they were essentially the same thing, and added that the Rezblock may be a percent or two more dilute.. "negligible difference" (
but in favor of the extract)
I wish 420 Science wonderful success, and I will use them whenever I can afford to, but I wanted to share in my discovery.
I do encourage use of the Rezblock product... but for those who can not afford it, and wish to try this out...
the price is surely right... it equals $2.50 per half ounce
