My friend let me borrow the Diablo Wrath when my other paintball marker was away for repairs. This is a great starter gun, easily equal to the Ion in terms of performance but it doesn't have as many upgrades. This is great introduction electronic gun that allows you to get the hang of other electronic guns but doesn't require quite as much maintenance. However, like most basic guns you will have to replace the feedneck since the original does not hold onto the hopper very well. Another fun feature included in this gun is the LCD shot and timer, something usually only found as upgrades to basic guns or standard in high-end guns.
This gun performs nicely compared to other basic electronic guns. It is not as accurate as high-end electronic markers, but that is why they are more expensive. Compared to those, this gun can shoot 6-inch groupings at a range of about 30 yards, while a high-end can do the same for 50-yards. Whether you wish to add a few hundred more dollars for that privelege is up to you.
