Just received my order so I'll give a short review on it.
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
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.
