This vertical grip is the exact replica of the Tango down stubby vertical grip. Definitely a well made grip that features a non wobble design so that when you mount it on your rail it wont wobble at all. It also features a battery compartment that can fit something like a surefire lithium battery size. For about 30 bucks, i would say its not worth it though, a good price range for the vertical grip would be about 15 dollars, but compared to the tango down version which is around 70 dollars, its a better option to buy this promag version
Pros: Easy to use, reliable, well molded, can store batteries, etc
Cons: To pricey compared to other vertical grips, other than that no cons
