Review on Periha Submersible Protective Adjustable Temperature by Keely Simmons

I purchased this product for my aquarium, but it was a complete waste of money. Based on my observations, it doesn't maintain a steady temperature and it stopped working after a month... This product doesn't meet the basic requirement of pet supplies and is a waste of money. The only pro is that it`s adjustable, but it's not worth the poor quality. Don't waste your money on this piece of junk..
