I had used this water purifier and I have to say that this is a good water purifier. It purifies the water totally and also contains the essentials minerials of water which are required by the body. Talking About its durability it is quite durable. All outside body is made of high grade plastic. It is very light weight and portable i.e we can fit this purifier in any place very easily. We all know that kent is a renowned company ffor water purifiers so its service is very good. I had called for servicing of my purifier the service agent comes on the next day. So I hope you understand and for purchasing water purifier take a look at this purifier also.
