I used this for my second child as well. I'm selling it now since I no longer need it. There are no particular issues with its use, and there are no noticeable scratches, but there are some minor scratches on the mirror surface from normal use. I will ship it in the original box. The following is a product description I borrowed from the internet: 【Baby Mirror for Cars ★ Wide Field of Vision for Fun】Product size (including base): Approximately 300*190*85mm (mirror surface size is approximately 260 x 160mm), Material: Acrylic (mirror surface), ABS (cover), Polyester belt (belt). The baby mirror uses the principle of reflection, allowing you to easily and securely check on your rear-facing child in their car seat through the rearview mirror while driving. You can check on your rear-facing baby, who you can't see directly, and concentrate on driving. The car baby mirror uses a curved mirror surface, and the very clear acrylic mirror surface covers a wide field of vision. You can clearly see your baby's face and movements. The image is also not distorted. 【Baby Mirror for Cars ★ Shatterproof for Safety】The mirror surface of the child seat mirror is made of safe acrylic resin, not dangerous glass, and has a tensile prevention effect, preventing shattering. Even if it breaks, it won't scatter, ensuring the safety of your baby and children. Also, the cover of the child seat mirror is made of ABS, an eco-friendly and safe material. 【Baby Mirror for Cars ★ Easy Installation with Integrated Design】Many commercially available baby mirrors require you to assemble the mirror itself, which can lead to it falling off. The car baby mirror is an integrated design, so there is no need to assemble the baby mirror itself or modify the car. Simply fasten the belt to the headrest. You can securely tie the adjustable strap to the headrest of the rear seat. More safely, more easily. Also, it comes with a detailed Japanese instruction manual that describes how to install it and precautions, so anyone can easily install it. Note: Please note that it cannot be used if the rear seat of the car has a bulge headrest pillow, as there is no place to secure it. 【Baby Mirror for Cars ★ Excellent Design for Peace of Mind】The joint ball allows for 360° free adjustment, allowing you to easily rotate it to any angle and find the optimal angle. Since the safety of parents and children is the most important thing, we have adopted a durable strap and buckle, and have also given sufficient consideration to load-bearing strength. The back has a soft material base that is gentle on the seat.
