The product does not contribute to hassle free cooking in fact it is troublesome. Firstly, The diameter of these bottles is large so it requires extra attention while handling them. Secondly, the bottles are prone to leakage while use, so an additional job of cleaning the kitchen shelves gets added coz of them. Thirdly, one litre of oil gets filled till the brim of the bottle, again inviting leakage even during storage. I really wish I had not bought them.
