I am rating this rest based on the fact it cost less than $25. You can spend more and you will get more. But, if you rarely need (or want) a steady rest, this is your item. It is made of sturdy plastic with padded contact areas where the stock of firearm will touch. It's great for rifles and good for pistols. Although it's made of plastic it's far from "flemsy" but very lightweight and easy to transport. The adjustable cradle has a large lugged nut to raise/lower and is easily actuated with one hand while looking through a scope. When you find your spot, just give the lock knob on the side a twist.
Pros: Great quality vs. price
Cons: Not very heavy
