Worked great on Granite.  I bought thid blade and 4 other blades to install granite on my kitchen and all I really needed was this blade.  Wirked blade on saw and grinder.  Kitchen later and blade is still good.

if you are expecting nice round pebbles your in for an unpleasant surprise. Golf ball sized rocks crushed to meet the size requirements. If you are planning to wash and reuse this will be a mess. I would have returned it but I was counting on using it and could not delay transplanting. I would recommend the original Hydroton in the clear bag.  The brown bag does a good job of hiding the 2nd Quality product. Not worth the couple of dollars  I thought I was saving. Did it work-Yes, Would I buy it again- Never.

I saw this product recommended on http://www.tilecleaning.org/grout-sealer-review.htm  so bought it.  My granite was just installed.  When I used this product on my kitchen island, it just beaded on it, so that portion of granite had been correctly sealed by the manufacturer/installer.  But when I applied it to the long rectangle of granite in front of my kitchen sink, it soaked it up like a sponge.  I used TWO applications to that area, so apparently the manufacturer/installer had missed that area when sealing.  So glad I bought and used this product.  After I have my new backsplash installed, I am going to use it on the grout.

This product was extremely difficult to use. It did not stick well to the countertop and pulled up all over the place when trying to apply it. It also bubbles terribly and is very difficult to get a smooth application. It's basically like trying to apply a giant smartphone screen protector. The image printed on the vinyl was also very pixelated. It looks nothing like actual granite.

These bits are awful for trying to get through stone. I broke pretty much all of them after only a few seconds of touching the stones. I would not recommend someone to buy these I will be seeking a refund

We had the Giani Granite finish applied on our bathroom countertop by a professional.  It looked great for the first month or so, then we started getting chips and areas where the finish was pulling away from the sinks.  We have been very careful so as not to damage the finish, but it doesn't seem to matter.  We wish we had just spent another couple hundred dollars and gotten real granite.  I would not recommend this product.

I use this for an unconventional purpose. I glue sandpaper to the surface and use it to lap my hand plane sole or anything that needs a straight edge. Normal granite surfaces are $60+ a piece, this is 1/3 that price and is basically the same thing only without the flatness certification. I checked and it is definitely flat enough. No light shines through my straight edge.

The paper towel holder is very nice, the reason I didn't give it the other two stars, is that it slides all over my granite countertops. Doesn't stay in place. It needs some kind of rubber grippers on the bottom of the stand.

The mouse laser loses tracking on my granite countertop. It only happens for less than a second, but it happens often, approx once every 10 seconds when mousing. My countertop is a black, lightly flecked granite. I imagine if you have a lighter colored heavily textured granite you will probably be OK. However, I have used several other mice on this countertop, mainly microsoft ones, and have never had a problem. One thing I noticed is that the mouse laser is much less bright than the laser in my other mice, this may have something to do with its lack of sensitivity. I am going to buy a microsoft bluetooth mouse instead.

used it on stone and concrete patio works really fast to remove high spots but wears down really fast compared to the masonry cup types that look like they are made of grinding stone material. also scores stone badly wile the latter mentioned cup leaves a smooth finish.

I wanted a device that could inject mortar into cracks.  This device is useless for that task.  Even with a very wet mixture of Type S mortar, after two of three squirts, the mixture would not come out.  Examination indicated the water was squeezed out of the mix about three inches from the tip and the dryer mix would not squeeze out the tube.  I tried several times and every time the gun would no longer squeeze the material out the tube.  I finally made the mix very wet but the gun did the same thing.  This gun may be useful for some things but as far as I'm concerned it can't be used for mortar.  Don't waste your money!

Looks nice, but does not stay stuck to my sink. We just installed a granite composite sink and the suction does not work on these sinks. This holder is really useless to me.

Working in stone in an artistic way, I had need for a stone glue that would cement two pieces from the same stone. The glue
was hard within the prescribed time. It did not perform well because I had to reglue several times. The process was embarrassing
as I was dealing with a client/student. Principally, it was too soft and did not hold up to minimal stress levels. For simple gluing this
would be OK. But if you want permanent, don't use this product. I wish I could return it.

I am a huge fan of full size Pfeil gouges.  These must be made of a different steel - cutting edges do not last.  I use honing compound only and the cutting edge has "chipped away" on several tools after light use.  These may be designed for use on basswood - not usable on hardwood.  Very disappointing.

I used this for jewelry making (attaching stones to metal), and honestly it wasn't very good. It dries very rubbery, and stones would fall right off. I now use an epoxy, which is much more sturdy and not rubbery.
