I purchased this about 10 months ago and used it from September until recently. I used it for things like picking up and dropping off my siblings and shopping, and it was very convenient as it turns into a stroller in one action ^_^ It's easy for children to push when the handle isn't extended. It can be used up to 1 year old, but my child is large and it has become cramped, so I am selling it. It comes with a dedicated storage bag and a mosquito net-like item. I haven't used them, so please check how to attach them. Please check the photos as there are some scratches, and purchase accordingly. - Model: Doona+ Infant Car Seat Nitro Black - Manufacturing Date: 2020-10-12 - Expiration Date: 2026-10-12 - Color: Black - Features: Can be used as a car seat Doona Type...Child seat Function...Travel system Baby seat
