I found it very useful if you need to stretch out the distance and you want to keep it light as possible but personally I’ve stopped using it as I like to close the distance as much as possible.
Nowadays I rather pick up the 5th leg which makes my quad stick bulky and heavier but if Im out fox control and I want to stay at one place for a longer period of time I can rest my rifle.
At the end of the day It really depends what type of ground you shoot at, what is your rifle setup and what is your preference. For the price I think it’s definitely worth to give it a try and see.
