I’ve been using this filter since 4 years. There are many pros to this model than cons.
Pros:
1) it doesnt draw much electricity
2) the catridge lasts longer than expected
3) the filter has indicators ( power on, uv on, tank full)
4) better than RO purifiers as water isn’t wasted
5) convenient size and weight
Cons:
1) if there is no electricity and no water in the tank of the filter.then you dont have water till the electricity is restored.
