We bought the "Blue Leaf" model last month and whenever my mom tries to
put tomato chutney using this jar, the cap will be thrown within couple
of seconds.
We called the service centre & complaint about this issue. That
week end service engineer came to our house & started to
convenience my mom saying that she could haven’t closed the jar
perfectly. Then my dad bought 1/2 kg of tomato to proove this one.
Service Er. put all the tomatos in the jar & switched on the mixie
with some over confidence. Suddenly jar cap had been thrown & his
shirt was completely filled up with tomatoes.
After this, service er. took the jars to his centre & came back to
our house after 2 days and said that u shouldn’t use these jars to
grind tomatoes!.
My analysis is that the jar closing mechanism is not designed perfectly
to handle the motor speed(750 watts). Previous model(CHEF-** Model)
seems to be OK.
So my recommendation is that don’t go with this "Blue Leaf" model. It is one of the worst design from Preethi.
