Kent is one of the most overrated brands dur to their extensive advertising.I beleive they seem to a good job in their brand but still the quality lack to the expectation of their promotion.There are many variants and each of them provide a really good variants.The expectation is all bogus to their advertisement but a decent one as there are more.better brands that can replace with lower cost.sustainance is very good though as they can make a really good experience from the above product
