Elena Litvinov 1 Returning immediately as my 3 year old opened the buckle in the first 5 seconds of sitting in it. Terrible buckle design and easy for children to open. Google it - not an isolated incident. Glad my son did it so quickly so I knew immediately to return this. Truly amazing how a company could sell this product. Their advice to customers with this problem is to tell your toddler not to do this.
