Nice car seat for the price, only thing a little frustrating is when its in the rear facing position you can’t access the recline lever without uninstalling it as its located under the seat on the front.
Just received it so can't comment on use but the installation was easy and the fact that it fits between my existing carseat and booster seat is great! Very impressed so far
Evenflo - All4Stages Slim Plus 4-in-1 Convertible Car Seat
I recently purchased the Evenflo All4Stages Slim Plus 4-in-1 Convertible Car Seat from Little Canadian, and I’m very satisfied with both the product and the overall shopping experience.
The car seat arrived on time and was delivered in perfect condition, with secure and careful packaging. The quality of the product is excellent, and it feels sturdy, safe, and well-designed for long-term use.
I also found the price to be very reasonable compared to other online retailers and physical stores, which made this purchase even more worthwhile.
Overall, a smooth buying experience and a great value for money. I would definitely consider purchasing from Little Canadian again.
