they fly true as long as you hit your target,if you don't they bend,rocks and hard surfaces are out so don't miss.
solo sirve para una vez de uso . bueno bonito y barato
my husband is very happy with these!
all 6 arrow we're bent had to send back the product only was just bad. but i was able to send back with no problems
Very cheap. Fletchings were falling off just from reviewing from the package and so were the inserts. These bolts are not to spec.either. If you have a half decent crossbow these bolts may ruin it.
These arrows were very cheap in quality, half of the fletchings fell off in the packaging before it was opened. The bolts shipped were 17&#34; long instead of the advertised 16&#34;. I would not order these again, very dis-appointed.
These arrows only fly straight with field points and mechanical broad heads.Good price for what they do.The 16 inch bolts are hard to find.
These arrows met my expectations. Came packaged (for shipping) well enough that they weren't bent as others stated on other bolt reviews. I've shot the same 2 (one with field tip and one with broadhead) repeatedly into a target and haven't sustained any damage/bending to the bolts as of  yet.
The bolts are nice and well constructed. Unfortunately I picked a lousy crossbow to use them with. Spend a few extra bucks for a good crossbow and pick up some of these bolts to go with it.
Answer: no
