These are generic roller string trees that you can find on many different websites at a similar price. They're great if that's what you're looking for, but I realized that they don't fit Strat style guitars very well, both in aesthetics (debatable) and in function. I bought a Harley Benton Strat here (ST-90SA Swamp Ash DLX) and these to go along with it but if you look at the stock trees of the Harley Benton ST guitars you'll realize that these are too tall for both the left side (D & G strings) and especially the right (B & E strings) since that original tree sits much lower.
The quality is not great either which is to be expected at this price point. I ordered two and one came in broken at the wheel part, which is fine bc I decided to keep the original trees and just slightly sand the insides of them for smoother action.
Overall I will give these a positive rating because they are great if you know exactly what you're looking for, which in this case is basic roller trees.
