Arrows come 1 inch shorter than US AMO standard. The Chinese company that builds them uses non standard measurements.Their incorrect measurement includes the tip which is removable. If you want a 31 inch arrow shaft you need to order a 32 inch arrow. I have a dozen arrows that are cut too short and to date no resolution to the problem. They ship China post and the shipping time is also very long.

Why two stars and not one? They are solidly built arrows and well packaged. They weigh in about 25% heavier than one of the US name brands but that is acceptable. Good price.

They seem fairly well constructed overall but several things make this a 2 star review.
For reference, I'm shooting these out of a #30 recurve.
1. The spine is, I'm guessing, weaker than the advertised .500.
2. The feather fletchings are attached fine, glued and tied at the front. But the feathers are very stiff. They break in, but are of very low quality.
3. This is the killer that makes this review low. The nocks on these are LOUSY. Really bad. Super tight compared to the better nocks from Easton or Carbon Express that I'm used to. The serving on my string is not fat either. Very standard 14 strand endless loop. This makes these arrows grab and fray the serving unless the nocks are adjusted a LOT. I'm talking drilled out and spread open a LOT. Some very minor adjustment of nocks is not that unusual, but these need either rebuilding or replacing.
That said, if you want to spend the effort on the nocks, these make ok 'beater' arrows. But really, if you're going to spend any money at all on arrows, get something decent. These will do nothing for your form, accuracy, or enjoyment of archery. They'll only hinder your progress.
Of note, I'm writing this review for two different products here on Amazon. TTAD and AC Archery. I bought a dozen from each (before I knew anything about arrows) and they are basically identical in materials and construction. I'm betting they come form the exact same factory in China.

This company does not use the AMO standard measurement. They are measured from the end of the tip (when screwed in) to the end of the nock. Which means they are about an inch too short for me. I complained and they said I should have ordered longer arrows if I needed longer arrows. However, I based my needed measurement on the AMO standard. I always buy 31" arrows and they are perfect. These are too short for my draw length. The company wouldn't refund my money, so these arrows will be my guest arrows.

There are only 2 reasons I gave these arrows 4 stars, instead of 5.
The first is that they are sold as 500 spine. When compared to some of my domestically produced 500 spine arrows, they are quite a bit more flexible.
The second reason is that a couple of them had uneven fletching, (see photo). The height of one of the three fletches was different by about 1/8-3/16". Like I said, this was only on 2 of the 12 arrows, and really didn't seem to affect flight.
That being said, these arrows are an EXCELLENT value!
I was headed to the archery range today and when I opened my front door, a beat-up cardboard box from China was sitting on my porch. I wasn't expecting delivery for at least another 10 days, so I was VERY pleasantly sureprised to see them there.
Given the condition of the packaging, I wasn't expecting too much from the arrows.
Again, I was very pleasantly surprised.
They were neatly held by foam keepers and appeared to be in great condition.
Once I got to the range, I donned my safety glasses, for the first few rounds. Fearing exploding arrow shards. My fears were unfounded, and I removed my safety glasses after the first couple of flights.
At 10 meters, they all impacted at a slight angle due to the amount of flex in them. Once I took them out to 20m, the flight and impact was fairly true.
The nock points were all perfectly aligned with the fletches, a small thing, easily correctable, but something that you don't always get with higher end arrows. Nice bonus!
I am shooting these arrows out of a 45# Cabelas Warden, takedown recurve bow, very similar to a Samick Sage.
I shot each arrow about 20 times, and they held up very well.
Like I said, they are a bit too flexible to be super accurate from my bow, but for stump-shooting, "beater" practice arrows, they will do just fine.
At some point in the near future, I will remove the inserts and cut them down to 29.5", (my draw length). If that doesn't stiffen them up sufficiently, I will give them to my daughter to shoot out of her 25# recurve. I am sure that they will give both of us years worth of shooting. That is, until we lose or break them; inevitable with ANY arrows...

For the price, you can't beat them!!

Although I don't usually order arrows on line, the price was great. I figured if they were junk my grandkids could and would use them up. I ordered 2 doz Oct 23 and they shipped Oct 25 with a arrival estimate of Nov 22- Dec 19, they arrived today. Packaging was in pretty good shape, although the postal worker crammed them in a standard size mail box with half the box hanging out toward the road. Upon opening the box the arrows were packaged well in holders and look awesome. The field points were separate in a plastic bag. They have regular feathers for fletching with inserts and knocks all done. I tested the spine and with little variation the are 500's,good for my 45lb recurve. I screwed in the field points, grabbed 2 and hit the backyard. Straight from the box they shoot very well, keep in mind I haven't cut them to my length yet. No issues yet with insert pull out. The knocks seem to be glued in. Will update this review after shooting these awhile, and trying out with Judo points and broad heads.
