V-Guard Companys Water heater of solar are not so very useful. It had been using by my cousin. As you know everyone use it mainly in winters and In winters most of days are cloudy so on cloudy day he dont get sunlight to warm water for bath. So he face problem.
But in summers for other purposes except than bathing it can be useful.( in summers we not need hot water for bathing)
Durability is quite good in this product.
Style is good but it is useless for him. No doubt its design also good.
Service and support of Comapny is quite good.
