Stability:
Because the base of the stand is just one long runner so you don't get much protection between the guitars when it is full. However, I have never had a guitar fall out or anything close so no major damage. There are some minor dings from me being careless so be careful if you are using this to capacity.
Quality:
Generally good, but you do find sometimes that the neck supports leave a black mess on guitars. This does blow/wipe straight off, but it isn't ordeal. This wasn't an issue at first, but after a while of use this does begin to happen.
Features:
The neck supports are structured in a variety of sizes to house acoustic and electric. This is helpful if you have a selection of types, but it isn't flexible for you to pick. It folds flight, so it is great for travelling!
Overall, there are stands that offer better protection but for the price this has served me very well.
