Customers report significant issues with durability, with many experiencing leaks from the bottom of the jar and the gasket failing after minimal use. This leads to a negative value perception, as replacement jars are often priced as high as a new blender. Concerns about leakproofness are widespread, with users noting that food and liquids escape from the bottom. The price of replacement parts is also a major point of dissatisfaction. Customers express disappointment with the brand, expecting better quality and longevity.
