+ i would definately recommend this gym because it has bright colors, bigger carpet than the others (washable) which even has clips to reduce the size and to create a border around baby. the hanging toys are nice, easy for a baby to grab, with minimum danger of getting hurt.the main unit has melodies continuous or not and 2 scales of volume and lights. also the arches are adjusted lower or higher depending on the age of baby. i believe that it is more suitable for babies from 3 months old to one year or maybe more, because of its flexibility. the price is a little expensive, but you won't need to change it in 2-3 months with a new one, so it has value for money.
- the battery is a little difficult to change it.
