This is the one of the best ups for my computer. it gives me one year warranty I am using this UPS from last 3 years. there is no problem come from this UPS. I love this product.
Durability is awesome.
Ease of use this best one UPS easy to use its backup is awesome from other UPS .when I doing my important work then current is gone then this is my best helper to save my important work.
