From October 26th, 2018 to November 4th, 2019, 50% user give 5-star rating, 50% user give 4-star rating. for Historial de Precios chrome extension.
The only thing I don't like is that it's still a bit buggy and I can't see the price timeline below the other menues, It appears that all the windows are overlayed one over the other.
Gran extensión, con mucho lugar para mejorar!
