This sand is very sturdy design and very sturdy construction overall I had a great experience using it what are doesn't seem to affect the middle and the Silicon is connected really well. It is very strong and he doesn't ruin it. There's a great by and for the price I feel to steal this type of section really be gone for around $100 and most other stores. One part I really like about these is that they don't feel like they will crack even when you put a lot of pressure on them that is really good compared to other kitchen items that are constantly breaking.
