Works great

Use mold release and you’re good to go! Very impressed with these. FYI this was with Alumilite Deep Pour and left alone for 7 days to cure.

Worked extremely well the mallet that comes with it not so well. But that may be user error. I forgot to put enough release on it. And was hitting hard and the top of it came off. Over great product worth the money

This is pretty easy to use and reuse. I'm up to at least 6 cycles so far and I'm sure I'll get much more out of it, maybe a lifetime. I use the form for live edge joining, so the majority of the form is filled with wood and the minority with epoxy in my applications. There are a couple of things to ensure the form works great: First, always spray one some mold release. I've never forgotten yet, and have had zero issues getting it out after curing. Most of the time, I don't even need the rubber mallet. Second, you'll need a good solution to hold down your wood so it doesn't float when you pour the epoxy. If you just try to clamp the wood down in a couple places, the base of the form will warp a bit leaving you a lot of effort to get your product flat after the epoxy cures. This is the reason I subtracted one star in the rating. I overcame the issue by cutting a 3/4" thick piece of MDF to the same size of the form, placing the MDF under the form, and clamping the wood down using the MDF as a flat reference. This is easy to do if I raise the MDF up under a couple of short 4x4's. I also level the whole thing with small shims or popsicle sticks so the epoxy levels out. If the form was thicker in the base, I might not have needed the MDF. But then the price might have been much more and MDF isn't very expensive. You can use anything that is stout and flat, but unless you like a lot of sanding or own a big planer, you'll want to put something under it! One other annoyance others have noted: The base and the walls of the mold are slightly curved where they meet. So if you are trying to get a 90 degree joined piece of wood flush to a wall, you can't. I found I can easily overcome this issue by using a 1/8" roundover bit on a router on any edge of wood I want flush to a wall of the mold. I have a router table so it really doesn't take much time and saves epoxy.

For me I'll take these over the flimsy silicon molds any day. They work well especially using mold release, just like the silicon ones. They hold their shape and don't bow out especially on the larger molds. They are flat and have a few degree angle that aids in resin removal. They are also much more affordable and durable.

They work ok. They aren’t 100% flat, because they’re thin hard plastic. Make sure you add a mold release to make it easier on yourself. Yes a silicone mold is night and day vs hard plastic.

Good sizes on both, which can make serving trays that are useful - although I like the bigger one better. They release pretty well (with releasing spray) and are easy to clean up.

Nice

Los moldes funcionan bien para lo que se diseñaron, son robustos y evitan que la placa de resina se ondule por el peso.
