Siliskin Sippy Top (2-pack) by GoSili

These are genius! Perfect to bring out and about for the baby or toddler who's just getting the hang of drinking.

I wish they were more durable

I really like the idea behind these. They're great for a quick sippy cup, either at home or when we're out. But ours quickly got small holes in them, and as I continued to use them, the holes got bigger until they were useless. Our 13-month old hasn't totally figured out how to take them off, but I'm sure that's coming. Mostly she also likes to chew on them, which oops - makes tiny holes. So I'll be looking for something else for her.

Good idea, bad execution

The idea is truly genius, but the slit for drinking in the silicone nipple is too effective at preventing spills... i.e. it's impossible to drink from. We ended up cutting the slit to be larger and then added a cross slit (to create an X shape instead of a single straight slit) and it still takes a lot of effort for my 4 and 2 yr old to drink from it. We will still use it, but I would recommend going for another sippy cup over these.

Both broke within the first two days

These are very thin and did not withstand putting them on our small metal kids cups. One tore right when trying to put it on, the other when our son dropped his cup accidentally. Nice idea, but I would not buy them again.

Tiny slit makes drinking impossible, encourages biting

I bought these for use with my almost one year old, but she couldn't get anything out of it. I checked, and the one tiny slit it has was sealed shut, so I manually yanked it open. I had my five year old try it, and he could barely get drink still. So, I tried too, and it's just almost impossible drink from. The spout is too thin, and the slit too narrow. It encourages a child to bite and chew on it, because the slit is such a crazy slow flow. I was really disappointed. For the cost, I could have bought two hard-top sippy cups. These are a great concept, but poorly made. I hope MightyNest stops carrying this, and finds a better product.

These did not work for us. I had a hard time getting them on glass cups without spilling and my two year old peeled them off in less than a minute. We are trying to limit plastics but this was definitely not the answer for us.
