  "answer": "Cybex Aton G2 Base: The SafeLock belt tensioning system is claimed to give quick, simple and secure installation with vehicle seat belts.\nChicco KeyFit Max ClearTex: The video demonstrates installing the base with either LATCH or the seatbelt but never both, adjusting the recline foot until the bubble is between the lines, connecting the lower anchors and pulling the strap tight, routing the seatbelt and using the lock-off, and clicking the carrier into the base until it clicks; it advises reading the manuals or consulting a certified technician.\nJoie Baby I2320AA: Under 8 lb, anti-rebound base locks with lower anchors or seat belt, anti-rebound bar reduces movement, base reclines four positions, can install with or without base; setup was a breeze and lower anchor install quick.",
