They work well if you prepare them correctly

I use these for early season bow hunting.  If I allow at least an hour to soak, they do very well.  The water they soak in doesn't have to be cold although that helps.  I usually put them in a ziploc bag right before I start the drive out to the hunting grounds and it works out great.  They will last for a couple of days without needing to be replenished.  So far, I am very happy with them and would recommend them highly.

These work well.  You do have to hold them down when pouring in the egg so that it won't run out.

Thes are awesome, and very well made. If you are measuring powdered ingredients, you will have to smack them pretty good to get it all out since they do stick a little being silicone. No big deal though, they're great.

If you buy these, they are good by the way, don't forget you might need some of the soluble kind as well.

They work well, but are a little filmsy. Have to be careful with them.

You have to work at them and they aren't fluffy but they do work pretty well and you can use the same pair for a good long while before changing.

These are good if you put them in the right spot. Certain spots give issues for some reason. They are good but not perfect.

These work well if you cook them right away. Dont let them sit for more than a couple days in the fridge.

They work great but heed all the warnings, they break easily so dig a little hole first before you put them in place and carefully place the bottle in it

No issues with these which I used with a low carb English muffin recipe. I realized after I cooked with them I wasn't sure if they were dishwasher safe or not -- there is nothing on the packaging one way or the other -- so I just washed them by hand. I see now on the listing that is recommended. I had sprayed them with cooking spray so nothing stuck anyway. The muffins came out delightfully round and the rings popped right off.

They seal well, freeze well and microwave well. If you're looking for a MealPrepSunday type of thing, these are what you want.

I bought these to make different shaped pancakes.  They work well there is just a little bit of a learning curve to them.

These worked out great for my family. Yes, they are delicate, but as long as you treat them correctly, they should last for a long time. They also survived the dishwasher, top rack.

If you follow the instructions and install it correctly, these work wonderfully.  They are very solid.  The recipe I was using called for 55 coals on each side, and these didn't budge.  I wound up having to dump more charcoal in part way through, and they held up even when I just dumped the bag over.  Sorry to the reviewer who said these were falling over, but they didn't install these correctly.

They work well. They grind very finely and are easy to grind. You don't have to turn hard to make them work. I put a mix of sea salt, dried garlic bits, cilantro, and red pepper flakes into mine. Makes a great seasoning for cooking.

make sure you follow directions, fortunately once you buy you will have them for life with their warranty

These are great, but use of a few less ingredients would be preferable.
