This seat is super easy to install as each isofix anchor can be attached independently, once installed it is very secure with very little movement. It feels really safe. Depending on the angle of your back seat your baby's head can fall forward even when fully reclined. This doesnt happen in my car but does in my husbands car as his back seat angles down. The swivel mechanism can occasionally be finicky and sometimes i have to give it an extra wiggle before it will spin. You also have to sit the seat all the way up before it will turn, so if baby is asleep, this wakes them. It has little loops to hook the belt out the way but they are near impossible to use. I do find that you can just hang them over the edge and they stay out the way fine, Because of the high and low strap covers the straps tend not to twist like in other seats, this saves me a lot of frustration. The buckle can be fiddly to put together but clicks in easily and is easy and smooth to fasten and loosen. I never used the sensor safe, Overall a very safe and easy to use seat.
