I really HATE the horrible blue colored air-stones, they look terribly artificial in a natural-style tank. But I also like aeration in my tanks. When I saw these I thought, "How Awesome, they aren't that blue color!" and the first one I purchased, in spite of the bad review saying it arrived broken in half, came in perfect shape. It fell out of the packaging, but was intact. I loved it so much, I purchased two more. But they arrived snapped in half. I might try one more time, but fear the worst. If you want a more natural looking air-stone, this is it.... if you can get it whole. 5-stars for when it arrives whole!I tried the first one, and all I got was some bubbles at the top of the product. So, I thought maybe I got a defective one, so I tried the second one, and it did the same thing. So, I tried the third one, soaked it for awhile, then hooked it up, by it self to the whisper air pump, and again all I get it some bubbles at the top of the product. I did not get bubbles up and down the airstone at all. I took out the third one, and the top part came right out. These are cheap, do not work, do not give bubbles up and down the airstone. I tried all three of them, and could not get any of them to work the way they should. Not a good product at all. The little tiny one inch air stones work way better than these. I was very disappointed, as I wanted these to produce the air up and down the 6 inch air stone for the corner of my tank. Buy at your own risk, but I wouldn't. If I hadn't opened and tried to get all three of them to work, I would have sent them back for a refund.Got it in the mail and the top plastic nozzle where it attaches to the "sand stone" was broken off. I suppose the glue used doesn't hold to porous sand. No biggie as I used hot glue to re-attach, and surprisingly enough it worked better than my $5 air stones!Dont hesitate to buy, just make sure you got glue handy as the glue used doesnt hold up very well.Well, I found where the stone, attaches to the plastic piece, that attaches to the actual air hose, is pretty fragile, and breaks easy. I broke the first one, but it was an easy fix to glue the plastic part back into the stone, but make sure you put your air hose on it, before you glue it back !Very disappointed in this air stone. Soaked it over night and installed into a 10 gallon tank. At first bubbles only came out of the very end where the air tubing connects to the stone. After playing around and making sure it was perfectly even i now have 3 tiny channels of bubbles but still not enough to aerate the tank. Never had problems with an air stone before and we have them in 5 other tanks, different brand. Honestly even for the price It's not worth it. For 99 cents at the pet store you can get a ball shaped one that works awesomely.Well, like the title said one arrived broken. For $1.99 it wasn't worth sending it back for replacement. I'm using the good one now and it works fine, as expected. I think in the future I'll just buy air stones from my LFS. Supplies are usually cheaper on amazon, that's why I purchase from them. But this is the first time I bought a air stone, which us sort of breakable. So, lesson learned.It works well, but it is no where close to a bubble wall. Bubbles only come out of one hole. It does the job though, so I'm giving it 3 stars.Not the same sand stone sold by Petco stores. Much lighter and not shaped like a rod but rather a long square shape. The ones sold by Petco stores works much better.I bought this as an add-on. The price seemed good. Too bad it arrived in three pieces. This was just one of three JW Pet Company air stone I bought and all three either arrived broken into pieces shortly are they were installed. Day your money and the tank clean-upI ordered four 12" stones and two of them were broken in two upon receiving them. I asked for an exchange for the two broken ones and in two days I received the two replacement air stones, of which one of them was broken. If you get the air stones, I suggest getting the shorter ones that would have a less likely chance of breaking in shipment. Or Amazon could package them a little differently.I received the pack already broken i give up send back for the price you pay you get the worst quality airstone.I try to fix it but wont work.Go somewhere else where you can get a decent quality..Never again ...I ordered this product excited to place it in my fish tank only to be disappointed. when i opened my package it was already broken. I emailed amazon and in no time they sent m another one but unfortunately it was broken again.This item is not working properly.In a general way, JW Pet stuff is very low quality.Returned and will not buy JW Pet in the future
