I have had my Viper for a few days now and have shot it a bit. It is my first crossbow so on most points I have no base for any comparisons, but the trigger is good and the bow is accurate and powerful. The cocking and de-cocking features of this bow work as advertised, and they are simple and safe to use

In one instance during sighting in I accidently found out that it will blow an arrow through a pressure treated 2x4 at 20 yards. I would not recommend shooting through 2x4 lumber as it is seemingly tough on arrows. The scope is good for a "Made in China" product and should serve nicely.

The crossbow package came from Wyvern. He was easy to deal with and puts together a fair package. I got a bow from his first shipment of Vipers from Ten Point so I guess I am one of the first to receive a Viper.
