It is a smart solution and much preferable to plain boards. However, in our case at least with the stroller (Cybex Priam), it comes quite far back resulting in me slightly hitting my legs while walking. Also, on sidewalks, okay I assist with my foot when going down or up, but on stairs it is reasonable that the child has to get down, but it is also difficult to lift it backwards. It hits the next step and hinders easy ascent. Of course, if you have an elevator, this probably doesn't concern you much.

Very practical, you can fold it up when you're not using it on the arm that holds the cart with a clasp, it fits nicely low and has not caused any problems even on quite uneven ground

Maybe I should have put 2 after all. Although the stroller I have is from the same company, it didn't fit and we had to make it work with a workaround. When it's in, there's not much space and it's not convenient for pushing the stroller.

It's amazing! It served us tremendously, it is stable (even on potholes and cobblestones) and very easy to install! We have a Joie stroller and it matched perfectly!

Awesome universal, I have been using it on 2 different strollers for 2 years now. It is very well made and extremely durable. Everyone asks for information at the playground.

Very good gadget, my oldest child is quite comfortable, the only thing is that it is not very stable and much more with our roads here in Greece, it leaves a lot to be desired. Otherwise, it is very useful, a bit expensive for what it really is.

Noisy a lot... helpful indeed but only for a short while... I personally didn't use it much. Not convenient at all for sidewalks and not very stable. However, for open spaces with smooth floors (e.g. a mall), it's nice if the big child gets tired and wants to sit down, my son liked it. It's a somewhat more economical solution (at the 70 euros I bought it) if you have 2 small children and you're alone on the walk.

It is very convenient, when we had the basket on the stroller, the older one had a good field of vision and loved this seat. Now that we have put the regular seat on the stroller, he cannot see straight ahead, but nevertheless he still wants this auxiliary seat, to rest during walks, he is not bothered at all that he cannot see ahead.
It is very easy to put on and take off from the stroller.
I recommend it for families with two children with a small age difference.

I believe I made the best choice! I didn't expect it to be so easy to use! It glides smoothly with the stroller, you can't hear the wheels, it goes on and off easily, and it folds up with just two movements!!! My 2-year-old son sits in it, which I didn't expect because he's not an easy child! He feels like he's with the baby in the stroller and we don't have any jealousy issues! Also, the fact that it has the seat is a huge convenience! The extra 20€ for the seat were more than worth it! It's also adjustable and even worked well with the basket!

The best for transporting both children. User-friendly, comfortable, lightweight, easily goes up and down sidewalks without any problem and without endangering the child. The seat is comfortable and necessary for the child to rest. I highly recommend it.

Fits all types of strollers, whether they face forward or backward! It has a quick disconnect feature from the girl! You can use it as a seat (like a bicycle) and as a rack (like a scooter)! Easy handling (at least with the Inglesina)! No vibrations! We have enjoyed family outings!

Convenient for the second child, but not suitable for the sidewalks of Athens. You cannot control the stroller when going up or down stairs, and your feet hit the wheels when pushing it. Very comfortable seat for the second child
