Bought a fllo to start our transition to three across in a smaller car. The seat does come partially disassembled so I'd set aside a bit of time after it arrives, however my daughter was eating lunch and actually took longer to eat than it did for me to get the seat together and the strap height adjusted for her size. Install is also very quick and rather simple thanks to Clek having videos to help if you're scratching your head. It took me less than 10 minutes to get a good, no movement install for the first time in the car. Personally the only disadvantage to this otherwise wonderful seat is the weight, but I knew it was a heavy seat before I ordered, so I wasn't disappointed or surprised at the weight of the seat. My extremely picky when it comes to car seats 14 month old loves her new seat and I am very happy with this purchase.

I don't know anything about how strong they are. I know the deal with the rolled wrenches. Its a awesome thing to know you have organized set, if your, lets say brokedown on the side of the road one-day
