Around one month ago I purchased a glen glass cooktop manual gas burner from the army canteen and this is a really good product of glen and I really like it and I bought it at rupees 2750 from the canteen and this is a fully gurranted product of glen and its burners are made of really good quality and its one burner is big in size and other is just little bit small than first burner and its switches to control the gas flame that they are really flexible and durable and its glass looks, style and design are really great as well as with five year waranty and its four burners have two year waranty and this is very durable product with great comforts and easy to use.
