Toy Cross Bow Pistol Gun Archery Set with Sucction Cup Arrows

The arrows fly about 2 feet and fall. This toy can easily be for a 4 year old if an adult makes all the string modifications. Even on the highest setting the arrows just fall to the floor without having gone more than a couple feet

I bought this for my 5 year old son who really wanted a cross bow for Christmas. However, after only a few uses it broke. We were able to fix it after the first time it broke but then it broke again.
