Rated 1 out of 5 by from Don't waste your money These moods are horrible!! Each store had a horrible seam and one of the molds broke and another warped trying to take the mold off. I really wish I would've gotten the slater molds. Don't make the mistake I did. Buy nice, not twice!!

Rated 5 out of 5 by from Easy to use I've used Slater molds for the 12" 14" and 16" atlas stones. They work great except that they require A LOT of duct tape. With the Hybrid molds you can make a nice stone with just some zip ties holding the 2 halves together. I went a step further and used some machine screws with washers and wing nuts to lock the 2 halves together along with a bead of silicone grease in the lip. Worked better than expected and had hardly any leakage from the seem.

Rated 3 out of 5 by from Great Mold I purchased the #275 mold a while back and have made several great stones. The only problem is that they are not even close to #275. They all come out around #240. I think this mold may have been mis-marked.

Rated 5 out of 5 by from nice molds I've made 8 stones so far,and am very happy with the results. having read some of the reviews and watched the videos- a few thoughts. i tried both zip ties and bolts, bolts give a better seam, but zip ties or bolts attached finger tight allow excess water to escape. Concrete excretes water as it cures and a looser joint makes for better drainage and a smoother finish. the biggest issue is getting air bubbles out, a cheap easy concrete vibrator is to use a sawsall with a rock duct taped to the end of a 12 inch blade, works really nice,my stones biggest voids are 1/4 inch or less, some have almost no voids at all.

Rated 5 out of 5 by from Easy to use These were really easy to use, I was worried about there being a seam but I used bolts like some other reviewers have suggested, making sure they were torqued evenly, and this wasnt an issue at all. Easier than messing with tape. I placed my 15.5" mold in a bucket as suggested and there was no damage to the stone or mold. I used an orbital polisher to vibrate the bubbles out, and it worked pretty well. Youll want to mix the cement wetter than what it says on the bag. The first one I made was too dry and only weighs 137lb instead of 160 and its all crumbly. It doesnt break when dropped on grass though. I may just try to put some concrete sealer on it and use it. I bet the garbagemen would be pretty mad if I threw it away...

Rated 5 out of 5 by from Awesome Super easy to use, throw some zip ties on it, mix the cement, and wait a day. Crack the thing open and you have an awesome toy!

Rated 4 out of 5 by from Easy To Use The forms were great for making stones. I would have given them a 5 star if they just would have provided the bolts and nuts to hold the forms together.
