## Customer Reviews

### ⭐⭐⭐⭐⭐ Good quality product.
*by O***E on 21 December 2025*

I got two of these for my twin niece and nephew. Works as advertised and they look comfortable when strapped in. Easy to install and a good value for money.

### ⭐⭐⭐⭐⭐ Very good product
*by A***G on 7 January 2026*

Top product, easy to install and great stability. Also looks good. Bought over 3months and still enjoying it

### ⭐⭐⭐⭐ Great for toddlers and older
*by N***B on 23 October 2025*

Great seat, great value for money, good fit and able to remove / fit seat and head inserts as required. Bought to be used occasionally. Easy to set up and install into car and seems sturdy. Child seems comfortable sitting in it and has adjustable head rest so seat can grow with child. Also great that is can be used as a booster seat for older children. I’m my opinion not suitable for babies and ideally for 2 years and up but also depends on height/weight.
