From December 29th, 2018 to March 3rd, 2019, 100% user give 4-star rating. for Novel Updates Tracker chrome extension.
Great concept, works most of the time but has tendency to be really buggy on occasions, had to drop several novels from tracking as they just constantly reported the same new chapters every 5-10 mins despite selecting read all. Wish subscribing from the novel page would be fixed as well.
Subscribing to the novel from the novel page was not available, but overall worked well
