5 out of 5 Gotta have em A staple

5 out of 5 Large supply With this amount of stones it should last me about 2 years at least. A bowl will last me a couple of days.

5 out of 5 Great product! Helps keep smoke dry and protects the bottom of the bowl. I've been comparing it with Denicool and so far I think deni keeps things dryer but these are much cheaper and do a great job too.

5 out of 5 Very good at what it's supposed to do Not as great as the Denicool crystals but pretty darn close

5 out of 5 Makes for a nice smoke I use these in almost all of my pipes

5 out of 5 They make for a better They make for a better smoke

4 out of 5 Peterson system? I see where these work with Peterson system pipes. I have 3 of them and want to try these. Will they help clean out the mess in the bottom, lol

4 out of 5 Not bad. I'm a wet smoker, can't help it. No matter what I do, the best case scenario is mildly wet. Dentists hate seeing me, 'cos of how much I slobber. Anyways, these work pretty good, overall. They don't affect the taste, but I think the Denicool crystals do a better job of keeping the bowl/smoke drier.

4 out of 5 Hmm Well they work. but i can taste the clay or something thats off but it not that bad.

4 out of 5 LaRue Living on the Texas gulf coast with ridiculous humidity levels can make drying tobacco a real chore at times. These stones definitely help reduce moisture when drying time is not wanted or even impossible! Are they a cure all? No. Will they help with unwanted gurgle? Definitely. And unlike some filters, draw is open and I have not noticed any change in tobacco flavor.

5 out of 5 Highly recommend These stones are great! Nice cool smoke while allowing the flavor to come through.

5 out of 5 Eriksen Pipe KeyStones The stones keep the smoke nice and cool just as advertised

5 out of 5 Works in all my pipes. These are great! I don't have that kind of pipe but it works. I always have gurgle in my pipe. I must be sloppy I don't know, I'm new to smoking. I really enjoy my pipe more. It really did work as described.

2 out of 5 Does ok While these do reduce the amount of moisture that gets through, quite a bit of moisture still gets through. I'll stick primarily with paper filters.

4 out of 5 Very interesting product! This is a very nice product, has kept the bottom of one of my pipes bone dry. It is not as effective with some of the aromatic blends in my experience, however they are still an excellent product.

5 out of 5 Eriksen Pipe KeyStones These things really work. Drop a few in the bottom of your bowl and get a clean dry smoke all the way to the bottom of the bowl. Highly recommended.

5 out of 5 Works great. Works great in any pipe. I have the Keystone pipe and the stones work great. You could have the wettest tobacco and using this system, not get a drop of moisture up the stem. I have used them in other pipes and they work, but you have to add quite a few to get the desired affect which reduces your bowl size for tobacco. So there's the trade off. But, I say again that these things work great.
