We had purchased two but then only used it sparingly in our second car. We've used only Clek products from when our kids were babies and have had nothing but great experiences. From the baby seat, to the Oobr car seat to the Olli booster. We particularly liked the Olli because of the Rigid-Latch system that Clek uses on their booster seats.
Rigid-LATCH (UAS) Connectors lock into place to provide additional booster seat stability. It raises your child 10 cm/4 in. to improve in-vehicle shoulder belt fit and better positions the seat belt on the child's hips to improve safety
You can hear the confirmation that latches are locked with an audible "click" which also provides a secure connection even when booster seat is not occupied
