This thing is amazing, I was a bit skeptical but I am so glad I purchased this. Rolled up it fits in my purse. It takes an adult two or three breaths to inflate it in just seconds Place the seat down make sure it's pushed all the way against the seat, stick child on seat and buckle them as you would an adult. No fiddly troublesome latch connectors to mess with. Only extra thing you have to do is slide the seat belt on either side of the hips into the metal connectors, only takes a few seconds for each side. Don't need to do any adjusting for this. Finally, if they need it if the top belt is too high like against their face, you use the shoulder clip. You use a slipknot connection to secure it on the side where the seat belt is extending from, and clip it to make sure the high part of the torso belt is placed snugly against their collarbone. If it's against their neck or higher, you NEED to use this clip for safety reasons Bonus tip, if you were like me you want to save a few seconds getting into rideshare and have it blown up already while waiting to be picked up. In the morning I'm carrying multiple bags including my son's backpack so I inflate it, put and put the carrying case and patch repair kit in my purse. To be able to swing it over my shoulder to have my hands free, I attach the shoulder adjustment clip the fabric loop right next to it so that it essentially forms a makeshift temporary strap like a shoulder purse. If you extend the shoulder clip belt all the way out and do the same thing by clipping it on to form a strap, you would have enough length to even carry it crossbody or backpack style. All in all I absolutely love this thing. Even with my first time using it, it took no longer than 45 seconds to set it up and adjust the shoulder strap to fit my son. Second time using it, it took less than 30 seconds. I have a 4-year-old who meets the minimum legal and safety requirements for this product. He weighs 42 lbs and 43 inches tall, the seat works perfectly for his size. He is happy because he feels like a big boy thrilled to have a break from his rear-facing seat However take note this important part regarding safety. The only time I am ever using this is when I will be seated right next to my son while using Uber or Lyft, to be able to him and fix the belt if he were to try to mess with it which would be incredibly dangerous. Just because your child needs the height and weight requirements definitely does not mean they are ready for a backless booster. These type of products are not usually recommended for young children because of maturity level. It's only safe if all the straps and everything stay in place, and the child isn't wiggling and moving around for touching/moving/pulling at the straps. Unless your child is very mature and you trust them 100 percent they won't touch the seatbelt, get something different or only get this if you will be right next to them watching all the time like I do. Most toddlers should not be trusted to be in the backseat alone with a backless booster. They often will put their arms over the chest strap which will put their life at danger if they were in an accident Also remember the lap belt should not be against their stomach. To be certain that it's properly fitted, it needs to be flat against the very tops of their thighs. Which is why it's called a lap belt and not a hip or stomach belt :) Here's a photo of my son sitting in his new seat for the very first time while taking a short 2 mile Lyft to school. He was a bit confused but now I believe he loves it, as it seems much more comfortable than a car seat! To deflate you just kind of poke your finger in the air valve to break the seal, and roll It up from the bottom. Deflates and is back in the bag in seconds. You can store the manual inside the case but I don't think that's necessary as it's so simple. Keep the repair kit with you at all times just in the unlikely event it starts leaking. And finally, a last piece of advice! Be very careful when zipping the cover up after you inflate it. Be careful that the the zipper teeth don't catch the white inflatable part or you may risk a puncture All in all, am extremely pleased and this product has exceeded my expectations. You definitely would not recommend it as a booster seat to be used all the time. You should always rear face your young child until they max out the seat for switching to forward facing, and max out that before switching to a booster.. preferably a high back one. The only reason I would ever recommend something like this is for maybe a spare extra seat that is ultimately used, or something that you need for travel like ride sharing airplanes and other public transport. As long as it's properly positioned they will be much safer, however a 5-point harness car seat is superior to anything else. Parents reading this, PLEASE don't consider switching to a backless booster once your young kid meets the minimum requirements. Just because it's legal does not mean it's back best practice and safe. The only reason my son is using this, is because I cannot realistically carry and install our heavy car seat every morning for our short Uber and Lyft rides. Hope my feedback helps someone!
