nothing is perfect there for no 5 stars, so here it goes star rating 4.75 stars they work great are really straight and accurat how ever that also takes your skills as well as a shooter and sighting in your arrow rifle properly as well , all that being said well worth the money to , very strong and can take impacts really well one of the 3 that came with my air javelin went 1/2 way threw my 1/2 Aspenite back board from 11 yards with the inlcuded field tip and did not get damaged at that time i have taken dozens of shots with my javelin and so far only killed off 2 arrows and iam shooting at card board boxes that are really hard pack with cardboard which is not ideal but works for now till i can get a proper archery target if you have a proper target then youll likey never damage any arrows at all or at least not to easy thats for sure. so in short
1 they are well made
2 takes a good beating
3 priced good as they are quailty made
4 accurate once you site you arrow gun in with them
5 pack a good punch even at 311 fps which gives you 36.52 Foot pounds of energy
