I have purchased this rod from the market of rupees 500 in the starting this rod do its work very fast it can worm the water in the bucket very fastly but after sometime I think 4 to 5 months this rod become very weak and do the same work which it done previously in more time. It take 4 times more time to warm the bucket of water as compared to previous. And after using this rod again and again this rod become more weak. And presently this rod is fully damaged. And their is not any warranty of this rod and sometimes it gives light shock also. So from my opinion we should purchase this product.
