How long do the rocks last?

I personally found they were useless. I have two female chihuahas and my grass was as bad if not worse. Total waste of time and moneywill not buy again

About 3 months. They come with a sticker to put on your calendar when you should change them.

I'm not exactly sure the exact time, but probably 3 months for me and i have two dogs drinking the same bowl of water.

I'm sure they would last beyond a year. I've had mine for maybe 6-8 months and some have changed shape a little, but otherwise they are all perfectly fine!

I've never tried rocks or outdoor gravel, however, the only slight problem I could forsee is impeding the rocking motion. It should definitely be on a stable surface that is even and doesn't tend to sink into the ground.

About 2 weeks on average. If the soil is more wet when the globes are filled, they'll last a bit longer.If the soil is less wet, the globes won't last as long. For a 17 day trip, we put 2 globes in our larger planters and 1 in the smaller ones and that worked quite well for the period of our trip. Though all the globes were empty when we returned, the plants were fine.

No Rocks came with mine Elaine! It came with fasteners for the base to secure it in the earth. I use it as a birdbath and put a rock in it with an electric ice melt for winter watering! Good luck with squirrels! They are everywhere!

I would say that small rocks and clay will simply take you more time. This unit is very powerful for an electric and besides, Amazon has a 30 day satisfaction program.

The rocks are heated by soaking them in hot water. You can buy a Sylvan hot rocks warmer, which has a timer and temperature setting --- it goes off once it reaches a certain temperature...

At least 2 lbs. I bought 2 lbs of rock and had to add a little more to get the right tumbling action.

Not sure on the lifetime. Also not sure about the stones - except I had at least two in my box - but that is not what I had planned to use it for - so I may look again and see. I assume after the stones are worn out you could purchase some new ones. Perhaps the User Manual has info on replacing them.

I have had two blocks in the tank for 5 months. It is my understanding from reading about them, they are good for at least 12-15 months.

Yes that is correct. And they are real rocks that have been cut and smoothed down. They are really cool, they come with bolts for bolting to a 3/4 inch thick plywood.

Himalayan rock salt will last forever...the bulb may burn out eventually, but your rocks will stay beautiful indefinitely. I keep mine on all evening very evening..it is very good for ionizing the air in a room so good for your health...enjoy!

No, the Great Stuff eventually disintegrates under the water and in direct sun. I tried it in between rocks and it did not hold. It may hold for a month or so. But not much longer.

Yes. The only thing to worry about is the rocks get dirty but it burns off.

No. They are separate pieces, and are wrapped separately. The rocks come in a bag.

I I would say around 1 1/2 inch diameter. Also I have observed that the rocks only need a couple days tumbling after the first grit. (7 days required on the course grit). Good luck

nope. I would argue that if it is out of flat the stone is either defective or used up. Should last years.
