I would highly recommend this product to just about anybody. It is very easy to put together, simple to fit AND strong enough to support even the largest baby (we tried ours on our daughter who is 12lbs and my cousins daughter who is 26lbs)
It is simple to put your baby in, just make sure she is on the sofa or something to slide the seat round her. The buckle and velcro system also makes life easy for you, and also ensures she is safe AND comfortable. We assume she is, since she cant talk, but a smile paints a great picture and she was in it for ages.
It fixes to a wall (it states a brick wall and over 10") but ours is plasterboard and it didnt cause an issue, and is easily removable, it sort of clamps either side but using a strong spring rather than screws or something similar to that. The straps also slide into the hanger, and it clips shut with a good noise, telling you all is safe, even if they arent done up it would safely hold her.
The height is also adjustable from both the main spring and the seat, and due to the way it is made, she will not hit her head. In the photo, you can see the plastic hanger, this stops her hitting her head.
I can honestly say there wasnt anything i disliked here, it works well, very well built and i can say very well thought out too. Highly highly recommended....oh and ours came with track and trace from Amazon as well.
