Just the quality to expect. The tubes will be good and chrome and the shocks will be universal. They hit at the same price point everybody else does, just wraps the two together in a little package. They will be the same rear universal shocks you can get all day long for 75$ from any vendor
They work just fine, lots of us have them. They are oversprung for sure but unless you step up to the 200$ range for shocks then that is what you get. 200$ rear shocks gets you Hagons sprung for your weight and more or less performance goals
That lefthand google search has endless pages about this kind of stuff
