Philips Aventถ้วยหัดดื่ม

I loved this cup and so did my 21 mth old son. I found it easy to clean and put together. Unlike other reviews, I didn't find it difficult to remove the silicone valve. I also liked that it wasn't a silicone spout as I find that these wear out quickly. My only problem with this product is I wish it would have a rubber base and also non-slip rubber grip on the sides of the bottle. This would make it easier for small greasy hands to grab and drink. I had to buy a new one within 2 weeks because it slipped from my hands and the base cracked. It didn't fall that hard - but it did fall on concrete floor. The second bottle also cracked - my son threw it onto the floor. Phillips please please make it rubber base and rubber grip on sides so it won't break so easily. Otherwise, love the product.
