Just received my order so I'll give a short review on it.
Pros:
1) Same length as regular Elite darts
2) Cheap price: 400 Homdox darts for $17.59 as opposed to 200 Koosh darts for $20.00
3) Fast shipping: Delivered in 9 days through Amazon
4) Soft head: HvZ and NIC legal. Note, the head is slightly squishier than Elite darts because the tip has thinner rubber.
5) Slightly stiffer foam
Cons:
1) Less accurate and more fishtailing than regular Elite darts due to : lighter weight and larger "whistle hole"
2) I don't have access to a chronograph but I've noticed a slightly slower FPS. Reviewers on Amazon also reported lower than average FPS compared to Elite darts
In short, if you have a HvZ game coming up in less than a few weeks, buy these cheap, slightly-lower-than-average-performance darts.
