I bought this immersion rod before 2 months ago I want to share my own opinion with you guys.
Firstly of this immersion rod is made up of cheap quality plastic material which easily melts after couple of uses.
Secondly the wire of the immersion rod is also very dangerous as it sometimes gives you electric shock even if there is no cuts or bends in the wire.
Thirdly it consumes more power and producing very less amount of heat, thus heating of a bucket containing 5 liter of water takes about 30 minutes which very much double than that of other brand immersion rods.
Fourthly and most importantly the customer service is pathetic as they will not solve any of your issues at any cost. Which makes this immersion rod totally useless and helpless.
As per my own bad experience with this immersion rod I will not recommend this to anyone. It's an waste of money product.
