Sure. In my opinion everyone should have a quartz crystal, they are way too handy to just dismiss. Even if you have a Bean there is so much you can do with quartz that you can't with a Bean.

The Bean does have several advantages over quartz frequencies.

-Community support, so you know you aren't getting ripped off. In addition, the creators of the device (Dale Fawcett and Jeff Sutherland) are very well-known researchers in the Rife community.
-The direction that the Bean faces does not matter. With quartz, the direction does matter - it has to be pointed towards you.
-The Bean can reach you anywhere in the world, without a doubt (if there is no EMF blocking you...). Have not done experiments with quartz in this regard yet.

On the other hand, the Bean is so much more expensive.

Quartz has advantages over the Bean.
-Quartz frequencies cut through radiation and EMF. The Bean, however, bonks out if you are in a WiFi-heavy area. Most people in the Rife forum have complained about having problems with the Bean reaching them.
-It can be used to transmute harmful radiation into beneficial radiation. This is why Orgonite works.
-The Bean does not have health effects besides that of the frequency you are running. Quartz does; it can have very positive healing effects. However it can go both ways; quartz could also be used to hurt people if you know how... But if you only use a positive offset this can be avoided most of the time.
-Quartz can be used for body alchemy. I will be explaining how soon. It was a discovery I made just last night. Basically, the crystal absorbs the frequency of everything it touches and sends the frequency back out - to you. So You can use this to send yourself supplement/vitamin frequencies through the air. But it only works in the presence of positive offset ionizing radiation, 30KHz and above.
-Similarly to the method above, quartz can be used to create homeographic and homeopathic remedies. You can transmit the frequency into water; the water will contain the energy signature of whatever is touching the crystal.
-Quartz can be used to affect the weather. Once again this could be both a good and a bad thing. If you live in an area with frequent rains, believe me when I say that they will get worse. LOL
-And by far, the most valuable to me - Quartz is CHEAP! Most people reading my blog will have a zapper and aluminum foil already, too. There is very little investment needed. Anyone can get started very quickly. I'm poor, you see, so I love things that are cheap and work just as well as $1000++ products.
