The seat is designed to securely attach with a lap and shoulder seatbelt and features 243 individual settings. It is foldable and lightweight for travel, and comes with a carrying strap. Users have reported both positives and negatives in their experiences with this device. REVIEWS: Happy with purchase, using for travel: The reviewer found this car seat perfect for their week-long trip to Chicago, as they knew they would be relying mostly on public transportation except for a few taxis/ubers. It is lightweight and comes with a carrying strap, making it ideal for travel. Great for Uber rides: Another reviewer used this seat primarily in Ubers during travel for a 5 year old, and it worked perfectly. While they wouldn't recommend it for long car rides, it worked well for multiple short Uber trips in NYC. Positive experience with adjustability: One customer found the adjustability feature of the seat great for growing kids, as it lasts from 4 to 8/9 years old. It is adjustable in different places to suit the child’s growth areas, eliminating the need for four different car seats. Quality concerns - flimsy and unsafe: One customer reported being concerned about the overall quality and safety of the seat, finding it flimsy and not very safe as it moved around a lot with the child and tended to bend forward. They were also unsure about the correct fit for their child due to so many adjustment settings. No response from company regarding defective product: One customer reported receiving a defective product that did not secure. They contacted the company a week ago and still had not received a response. Cannot be used inside airplane: One customer found the seat great for travel, but was disappointed that it was not FAA approved for use inside the airplane.
