I have one of the ED silicone molds in the basket. I chose the white silicone, so cannot say anything about the red. I like my mold. The only thing to be aware of is that when you fill it completely or even mostly full, your cut bars of soap are going to be very large squares. You can fill it less full and get more normal sized rectangular bars, but then it seems the mold is being wasted when it's not more full.
My bars from the ED mold come out to 3 x 3.5 inches after planing and beveling. I don't want to cut them in half because then they are too skinny. Another option is to cut them into a normal bar size and a mini bar size and use the mini size for travel or as samples, but again that seems a bit wasteful as well. I already have enough end pieces to provide me with more than enough travel size bars to last me a lifetime!
It is not a bad thing, the size of the bars, just something to be aware of before purchase.
