Anyone try these?

Dyna Beads are tiny, high density ceramic spheres that roll freely around the inside of the tire. As the tire spins these beads roll to a position exactly opposite the tire's heavy points, thereby eliminating any out-of-balance motion. (**scroll to the bottom of the page for a testimonial) http://www.bestrestproducts.com/celestia/imagelib/DB_closeup_400.jpg
The result is a smoother ride AND a better look - Dyna Beads eliminate the need for ugly lead crimped-on spoke or stick-on wheel weights on your rims. Unlike messy liquid balancing medias, Dyna Beads don't thicken or harden over time. When you need to repair a tire puncture they don't interfere with plugs or patches.
DynaBeads can be used in tubed or tubeless tires, and they also work for scooters, ATVs, or automobiles, and other tires. Contact us by phone if you have non-motorcycle application.
Dyna Beads dynamically balance tires on the move, resulting in a smooth ride that lasts the life of your tire. In fact, your tire will remain perfectly balanced until replaced. By contrast, a tire balanced "the old fashioned way" with lead weights can become unbalanced in as little as a thousand miles. You'll know when that happens because the handlebars start to buzz, and if you look at the front tire (while it's spinning on the road) you'll see it vibrating. That's because the wheel is no longer in balance. As rubber wears, the wheel gradually becomes unbalanced.
So how do Dyna Beads work? Imagine this scenario - you have a washing machine going thru the spin cycle with 3 pairs of blue jeans. As long as there's water in the drum, the machine spins in a perfectly balanced fashion, but as soon as the water drains out, the machine starts that old thump-thump-thumping noise because the load is unbalanced. Pour back some water (or in the case of a motorcycle tire add some Dyna Beads) and the load re-balances itself.
A more technical explanation goes something like this: The tire/wheel/ axle assembly is constantly spinning in an elliptical motion due to the inperfections inherent in tire and wheel manufacturing. If the wheel was perfectly balanced there would be no vibration at the axle, but because no tire or rim is perfectly balanced, you must add lead weights to smooth out the spin. An unbalanced tire bounces up and down because the suspension is storing and releasing energy each time the tire spins thru a rotation. It's a complicated ballet between the various components, with the heaviest point of the wheel pulling the axle off-center. Add balancing media (Dyna Beads) to the inside of the tire and the laws of physics will distribute the beads to a point opposite the heavy point of the tire/wheel asssembly, and the tire will return to a neutral (balanced) spinning point. The tire stops bouncing and any vibration goes away. Whew, enough technospeak!
For the adventuresome riders who change their own tires, and for those who travel to the far corners of the world and have to change their tires in the field, Dyna Beads provide a perfect solution to "field balancing" tires when there's no other method of balancing available. You won't have to rely on the "old red dot at the valve stem" method of tire balancing, hoping that the light spot of the tire will offset the heavy point of the rim (it seldom does).
So how many Dyna Beads do you need in your motorcycle tire?
Smaller bikes require 1 ounce in both the front and rear tires... order DB-2
Medium-to-large bikes require 1 ounce in the front and 2 ounces in the rear... order DB-3
Large bikes (Gold Wings etc) require 2 ounces in front and rear... Order DB-4
When in doubt, order the "next size up". Additional DynaBeads inside the tire won't hurt anything, they'll just help keep the tire balanced and they'll automatically redistribute within the tire, based on the natural unbalance of your tire. By contrast, not having enough Dyna Beads can result in an unbalanced tire because there won't be enough of them to offset the wheel imbalance.
How to install Dyna Beads
Here's a series of photos showing Dyna Bead installation using BestRest's exclusive DynaHose. The DynaHose is a long, flexible, pre-measured tube that contains the proper amount of Dyna Beads according to the kit you order. With the DynaHose there's no pouring or measuring of the beads, the beads can be carefully trickled into the tire, and the DynaHose can be easily snaked between discs and spokes. It makes installation even easier!
This is the BestRest DynaHose. Depending on the kit you order, your DynaHose will contain 2, 3, or 4 ounces of Dyna Beads. The DynaHose is graduated at one ounce intervals so you'll know how exactly many beads you've inserted. Pinch the hose to stop the flow of beads.

Here's the DynaHose next to the tire

Remove the valve cap, the valve stem, and any existing wheel weights
http://www.bestrestproducts.com/celestia/imagelib/DBH_valvecap_400.jpg
Thread the DynaHose between the disc or spokes. The flexibility of the DynaHose makes this much easier than the older applicator kits.

Remove the SMALL cap from the end of the DynaHose. The large cap remains in place.

Use the included ziptie to secure the open end of the DynaHose to the valve stem
http://www.bestrestproducts.com/celestia/imagelib/DBH_ziptie_400.jpg
Raise the other end of the DynaHose and slowly trickle the beads down the hose. A gentle tapping motion with one finger will keep a steady stream of beads rolling down the hose.

If the Dyna Beads get clogged at the valve stem, tap the stem with your finger and they'll quickly drop down into the stem.
When you've inserted the desired quantity of Dyna Beads, lower the free end of the hose and stop the stream of beads. Pull the DynaHose off the valve stem and cap the end of the hose.
Replace the tire valve stem, inflate the tire to the manufacturer's recommended pressure, replace the valve cap and you're done.
That's all there is to it! As soon as the wheel starts to spin, Dyna Beads will dynamically and automatically re-balance the tire. When the wheel stops spinning the beads drop to the lowest point of the tire and wait for the next rotation and balancing cycle.
If you have a tire pressure monitoring system on your bike, don't worry. The Dyna Beads won't interfere with the system or damage it in any way.
Dyna Beads don't thicken or harden over time like messy liquid balancing medias. And when you need to repair a puncture they don't interfere with plugs or patches.
Shhh... don't tell anybody... Here's a secret tip for the Frugal Rider - You can recycle Dyna Beads and reinstall them in your next new tire. Use a small paper cup to collect them from the inside of the old tire when you break the old tire bead.
