These arrows are just "ok", the weight is appropriate and the tip is adequate. The problem is that the vanes are not attached with any sort of consistency, so if you plan on using a tip-up or whisker biscuit arrow rest the vanes won't necessarily line up correctly. The nock is glued in place so when you nock the arrow the vanes may or may not line up correctly with the rest. There is no way to twist the nock without somehow breaking it from the shaft and resetting, but whatever glue is used is tough and unmovable. If you child has a simple non-compound bow these arrows are fine, if they have a more advanced bow then these arrows probably won't work.
